That defensive solidity begins with Unai Simon.
The Spain goalkeeper continues to rewrite history as he extended his remarkable run without letting in a goal at the World Cup to a record 609 minutes, keeping Cristiano Ronaldo and company at bay in Dallas.
“Portugal dictated most of the game, but Rafael Leao did not offer that extra spark, neither did the other substitutes,” said Balague.
“Spain defended in numbers and collectively, they tracked back a lot. They individually sorted out problems. So we haven’t needed a miracle save from Simon.”
During this tournament, Simon has surpassed Walter Zenga’s mark of 517 consecutive minutes without conceding for Italy, as well as his compatriot Iker Casillas’ benchmark of 476.
Ahead of Simon, Aymeric Laporte and Pau Cubarsi are at the heart of their defence, while Pedro Porro and Marc Cucurella provide the width from full-back.
That back-four has started three of Spain’s five matches at this World Cup so far, with Marcos Llorente deputising for Porro at right-back in the other two.
Balague added: “It also helps that Rodri is reaching his best version and he has had two extraordinary games – he is the lighthouse of the team.
“The partnership between Laporte and Cubarsi is perfect for the way Spain plays – moving the ball around, driving with it, and defending with a lot of space in behind.”
