Thanks for all of your questions over the past 90 minutes, but that's all from BBC Sport's football tactics correspondent Umir Irfan.

We're going to alter our route now and move in the direction of the next two games to come at the World Cup.

Canada v Bosnia-Herzegovina (20:00 BST) in Toronto

USA v Paraguay (02:00) in Los Angeles

Toby, Exeter: If England go out in the quarters with the attack misfiring, does leaving Phil Foden AND Cole Palmer at home become the defining mistake of Thomas Tuchel's reign - or is he right that you can't fit that many number 10s in one squad?

I think Tuchel is banking on a single tactical approach and making that the best version it can be – which is how recent winners have won the tournament too such as France, Argentina, and Spain.

Tuchel's side looks to get the best out of Kane dropping deep so runners from midfield are key. Palmer is less of a runner in behind and more of a creative 10 so fits into the plan less easily. Foden, as a goal-scoring attacking midfielder, could have done this role - but on-form Bellingham or Rodgers make sense. Ultimately you don't need four players competing for the same role.

Tuchel also wants his wingers to be direct, pacey dribblers and great one against one to push teams back. Palmer and Foden are different in this way to Gordon, Madueke, Rashford and Saka so again don't fit his general system.

It's all logical. Knockout football is unpredictable but the system in theory makes sense and he's picked players that fit it best. The rest of the squad give him game-specific solutions as substitutes.

George, Colchester: Hi Umir, will all of the 'underdog' nations go for a back five? Or will someone be bold and try a more offensive approach?

A football analyst I'm fond of and friends with, Roger Bonet, tallied the defensive shapes teams use closer to their own goal. It goes as follows:

4-4-2 (24 teams) ➡️ 50%

5-4-1 (9 teams) ➡️ 19%

4-1-4-1 (6 teams) ➡️ 12.5%

4-2-3-1 (6 teams) ➡️ 12.5%

5-3-2 (3 teams) ➡️ 6%

This is data from pre-World Cup based on qualifying games but only a quarter of the teams at the tournament consistently used a back five. Under pressure we may see back four teams move to a back five but we are increasingly seeing underdogs attempt to be aggressive when defending. It didn't work for them but South Africa looked to press high (from a back five). It did work for Mexico (who pressed high from a back four).

Sitting gives big teams the game they want - closer to the opposition's goal with 90 minutes to score. Pressing, although risky, gives some teams a chance to create chaos and win the ball high.

Kieron, Darwen: Umir, are England a better team when Harry Kane drops deeper to spread the play? Or is it better if he stays in and around the penalty area? Is there room for both Morgan Rogers and Jude Bellingham in the team?

Personally I think Kane is much better used dropping deep (and so does Vincent Kompany and Thomas Tuchel!) One reason is for for his ability to provide the team with great passing quality for runners ahead of the ball like Luis Diaz at Bayern, Son Heung-min at Spurs and now Anthony Gordon and Marcus Rashford for England.

If teams man-mark him when he drops deep, there is space left in the opponent's defence for the runners we've mentioned. If they don't follow him, he becomes a spare man in midfield, helping England keep good possession and with time and space he can play dangerous passes.

This tactic also helps him score, more interestingly. By dropping deep, he is slower to arrive to the final third. As teams drop closer to their goal when defending, space opens up in front of their back line. Kane often finds himself in these areas unmarked - able to score from distance.

There can be room for Rogers and Bellingham with Rogers on the left but it goes against Tuchel's system - I doubt we see it.

Tuchel wants wingers who are good one against one able to run down the line - think Gordon, Rashford, Noni Madueke. This helps push teams deeper and opens up space in front of defences for the likes of Kane, Bellingham and Declan Rice to score from. Watch the first goal against Costa Rica for a good example.

Jasper, Manchester: About France, people say that the team is tailor-made for Kylian Mbappe - to what extent is this true?

Didier Deschamps is one of the best coaches in the world at creating a team that looks at his players first. Other coaches can instead end up having a system they like – before looking to find who they can put into it.

For that reason, France's system is a bit hard to read.

On paper, it looks like a 4-2-3-1 but Mbappe (the striker) moves over to the left to play very close to the left winger. This was Hugo Ekitike before his injury but Desire Doue played out wide last game. These wider left attacking positions suit Mbappe more than playing him as an out and out striker.

Ousmane Dembele (the number 10) then moves into a more natural striker position and Michael Olise plays on the right. In that way it can look like a 4-2-4 that is quite lopsided.

Deschamps also plays Adrien Rabiot as the left central midfield to provide the running that Mbappe may not always do defensively.

We will see how it pans out but yes, the ideas make sense. Players are put in areas of the pitch that they feel comfortable in and some not-so-big names are selected for the qualities they bring to the team, to help maximise the likes of Mbappe.

Jake, London: Hey Umir - How crucial is Scott McTominay going to be for how Scotland are set up? Miss him as a United fan as he's one of a kind.

Big fan of McTominay myself and I think if Scotland are to get joy, he will likely be central to it. His ability to cover big distance, even in a warmer climate, will be one of his strengths. If teams look to press Scotland when they build out from the back, his ability to carry the ball up the pitch will give Scotland respite. He also makes sense as an aerial target when they go long.

As we've seen for both United and Napoli, he has match-winning quality. His ball-striking and threat from set-plays will be key if Scotland are to turn tight games into results.

In short, arguably their most important player for me.

Thanks to everyone who has shared their thoughts so far.

Paul, Manchester: We have seen a significant increase in the use of 'set piece coaches' in domestic football. Is this as prevalent worldwide, are we likely to see the widespread use of these in the World Cup, and will tactics from 'set piece coaches' differ between the different countries/regions in the World Cup?

Football is increasingly a globalised game and we've already seen the trends of the Premier League and the Champions League bleed into the opening few games and the qualifiers. Teams across the world generally tend to employ set-piece coaches or have one of their coaching staff increasingly focus on this part of the game.

For example, Mexico scored numerous set-plays in their games prior to the World Cup starting and Czech Republic opted to concede possession before scoring via a long-throw.

Especially against stubborn defences, there is logic to keeping the game tight and scoring via a set-play instead of taking more risks on the ball and potentially conceding counter-attacks so in a knockout competition I think we will see teams try to do so.

As for the differing tactics of set-plays per country - perhaps less so, although it would be fun to see. The Premier League's long-throws and in-swinging corners to crowded boxes were pretty effective so those ideas will generally persist (again, as seen in Czech Republic's approach v South Korea).

Seth, Ashbourne: Which current England player is most likely to become a future England manager? I'd have to say Jordan Henderson.

I would likely echo the Henderson shout. Defensive midfielders tend to make good managers because they see the greater picture of the game and as a captain he speaks well too. Having played under Jurgen Klopp, Gareth Southgate, and Thomas Tuchel now – as well as experiencing football at Ajax, it does make sense.

I also think Marc Guehi could. Similarly, a well-spoken captain, and although his time under Pep Guardiola was short, that sort of education is often enough to spur a career in management for many ex-pros.

As you digest reaction for last night's two games, why not also have a go at our brand new Who am I? game.

The rules are simple. Each day there's a new footballer and the challenge is to guess who they are in as few attempts as possible.

After each wrong guess you unlock a new clue. But, if you get your answer in as few guesses as possible, you get more points.

Three is a good score, four or five points is exceptional.

So, take part in quiz number one and return for more tomorrow.

Today's player and clues are set by BBC Sport's Flora Snelson.

MJP, Glasgow: How do you expect Scotland to line up against Haiti? Will it be different from how they shaped up against Bolivia?

Scotland under Steve Clarke are a team that are strong without the ball, especially when attacking big space. Against Haiti however they will probably have to take a more front-footed approach given the quality gap between both sides.

Against Bolivia they had 46% of the possession. Against Haiti, I suspect they will have a fair bit more.

Looking at their performance against Belarus (ranked 100) is a better indicator of the approach they will likely take.

Ben Gannon-Doak started on the wing in that game and provides more individual quality against stubborn defences so may get minutes. John McGinn tends to move in-field even if he starts from a wider position, and played on the left against Belarus. I think he may do the same again with Andy Robertson given license to push on.

Set-plays and the physicality will be key to help them break the deadlock if the game is tight too but that is something they do irrespective of the possession they have in a game.

Raul Jimenez's goal was the 46th for his country in his 125th appearance, moving him joint second in Mexico's list of goalscorers, behind only Javier Hernandez on 52.

Even when the game started, Jimenez was breaking new ground in his career.

He had previously made six substitute appearances in World Cup finals - one in the 2014 tournament, two in 2018 and on three occasions in 2022.

But, in his first World Cup start, he almost made an immediate impact, having a powerful half-volley superbly saved by South Africa's Ronwen Williams in the fourth minute.

Jimenez, who earlier this week completed a move from Fulham to former club Wolves, sealed the victory in the 67th victory to ensure co-hosts Mexico made a winning start.

Former England defender Gary Neville, speaking on ITV, said: "That is likely to be the greatest moment of his life from a football perspective, scoring in front of 80,000 in that stadium, in his home country. It is a great moment for him."

Ex-England striker Ian Wright added: "It was very emotional for Raul Jimenez. If it was me, I would probably feel the same.

"The thing about it is when he scores the goal as he runs off, you can see the realisation and that is where the emotion comes."
