When you look at the numbers, the only issue I'm finding - and it is the exact same problem in France as well - is Great Britain don't have enough players directly entering the tournament by their own ranking. There are only three British players in the top 100.

The difficulty comes from the other players receiving wildcards, which are incredible opportunities but you are most likely up against a player much higher in the rankings than you. Therefore, you have to cause the upset.

Great Britain have that young generation showing up, but they need to be inside the top 100 to give themselves a better possibility of going deeper into the tournament. Of course having seeded players is even better.

Great Britain's Arthur Fery was broken in the opening game of the second set, having lost the first set, and a couple of break-back points have gone begging for Fery in the following game.

Quentin Halys is back on level terms with 32nd seed and French Open semi-finalist Matteo Arnaldi.

The Frenchman broke Arnaldi's serve twice en route to taking the second set 6-1.

And with one massive forehand winner, Valentin Royer immediately cancels out Harry Wendelken's break advantage.

And just like that the tables can turn.

Two unexpected forehand errors from Royer, one a little wild and the second he was just a little bit too close to the net. Maybe a little bit of over-adjustment and I think he felt a little bit rushed and he rushed himself

Better news for Harry Wendelken, who breaks for a 2-1 lead in the fourth set, but he might be about to give that break straight back as he's 0-40 in his next service game...

I think the expectation is getting to Ben Shelton. He is the Obi-Wan Kenobi - he is the Americans' only hope of winning Wimbledon.

He served three double-faults and just two aces in the whole of that first set. He didn't have a break point at all, whereas his opponent had four break points and got one of them.

He looks a little bit off-balance. He has stumbled and fallen down a few times. It just looks like things are a little bit off. He is going to have to really get it together because this kid Otto Virtanen looks good.

Ben Shelton is fighting back in the second set against Otto Virtanen, leading 4-1.

He raced to 3-0 and also had break points in fourth game of the set, with Virtanen eventually holding serve after coming through three deuces.

Fifth seed Alex de Minaur has come through a tie-break to clinch the first set against Roman Andres Burruchaga.

The Australian trailed 3-0 after losing his opening service game but broke back in the fifth game.

A messy tie-break saw both players struggle to win points on serve and De Minaur wasted two set points before eventually getting over the line.

Up first on Centre Court shortly is defending women's champion Iga Swiatek, who starts her campaign against American Taylor Townsend.

Polish third seed Swiatek is a six-time Grand Slam champion but comes into Wimbledon in questionable form.

Following her fourth-round exit at the French Open, where she is a four-time champion, Swiatek began her grass court season with defeat by Emma Navarro in Hamburg last week.

Townsend is ranked 79th in the world but has never been past the second round at Wimbledon.

Crowds of spectators have gathered around a few of the smaller outdoor courts as more British players bid to join Katie Swan in the second round of the singles competitions.

I've positioned myself between courts 14 and 15, where on one court Harry Wendelken is trailing Frenchman Valentin Royer by two sets to one, and Jacob Fearnley is a set and a break down to American Alex Michelsen on the other.

The crowd on court 14 chant for Wendelken as he steps back on the court for the start of set four, and the volume level continues to rise as the Briton sets up an early break point - but the game ends in a hold of serve and shouts of ‘allez’ pop up around the arena.

Not so much chanting on Fearnley’s court just yet, but he will need some decent support as he seeks to turn this around.

A single break of serve is enough for Damir Dzumhur of Bosnia-Herzegovina, the world number 105, to win the first set against British wildcard Arthur Fery.

Fery was at 15-40 Dzumhur attempted to serve out the set, but those two break points went begging and Dzumhur, having missed chances to wrap up the set in the previous game, gets it done with an unreturned serve out wide.

I think Royer's confidence is very high and that's why he feels like he can be aggressive.

We saw Wendelken improving his first-serve points won at 86%, that wasn't the issue, it was the second serves where he was starting to have a little difficulty.

How much of that was down to being a little less risky on the second and how much is down to Royer being a lot more aggressive on those returns? I think it's a combination of the two.

American fifth seed Ben Shelton will have to come from behind to reach the second round after losing the opening set to Finland's Otto Virtanen.

There wasn't a single break point across the opening eight games but Virtanen seized his opportunity in the ninth, converting his fourth break point, before holding to 15 to take the set 6-4.

Harry Wendelken started the third set in decent fashion, but France's Valentin Royer won four games in a row - including two breaks of serve - to take it 6-3 and move one set away from round two.

Another big ace down the T on set point and Alex Michelsen is a set to the good against Great Britain's Jacob Fearnley.

If Wendelken's coach, Hamid Hejazi, was to tell him anything it would be stay patient as the first step because he really has started to get a little antsy.

Italy's Matteo Arnaldi - a semi-finalist at Roland Garros earlier in June - has taken the first set against Quentin Halys.

Arnaldi, the 32nd seed, has never won a main-draw match at Wimbledon, falling in the first round in each of the past three years.
