Lack of goals scored is the issue for clean-sheet kings Spainpublished at 12:37 BST
Spain v Belgium (20:00 BST)
Image source, Getty ImagesSpain possess an array of attacking talent and midfield riches that would be the envy of most nations.
Pedri continues to pull the strings in midfield, with support from 2024 Ballon d'Or winner Rodri, helping to provide the platform for leading front man Mikel Oyarzabal.
Real Sociedad striker Oyarzabal has weighed in with four of Spain's nine goals at this tournament, taking his tally to 17 in his past 17 starts for La Roja.
Barcelona wonderkid Lamine Yamal has not yet hit top gear, scoring his only goal in Spain's 4-0 group stage win over Saudi Arabia, but is gradually returning to full fitness.
However, Spain's tally of nine goals in this tournament is the joint fewest, alongside Switzerland, of the eight quarter-finalists.
It is at the other end of the pitch where the Spaniards have built the foundations of their latest World Cup challenge, as the only team yet to concede.
"You feel there is so much more to come from Spain," said former England striker Chris Sutton on BBC Radio 5 Live.
"The fact that they are not conceding is ominous for other teams. Their toughest test will come against France if they both win their games [in the last eight].
"I think Spain are capable of beating France but they'll have to be near perfect on the day."
Goals scored by the quarter-finalists before the last-eight ties:
- 14 - Argentina, France*
- 13 - Belgium
- 12 - Norway
- 11 - England
- 10 - Morocco
- 9 - Spain, Switzerland
*= France scored another two goals in their quarter-final win over Morocco, to take their total tally to 16 for the tournament
