Luis de la Fuente confirms Lamine Yamal 'won't start' vs Cape Verde in World Cup clash

The 18-year-old, who has not played since April due to groin and hamstring problems, has returned to full training and is available for selection alongside Nico Williams and Victor Munoz.

De la Fuente stressed that all three players are in good condition but will be carefully managed in Spain's opening Group H match.

"The good news is that Lamine is very fit," the Spain boss said. "He's following the set process, he's training very well, and he's in good shape. They're all available, but they won't start the match."

He added that any involvement will depend on how the game unfolds. "We'll have to wait and see how the match progresses and then decide how they can contribute. It's about the game situation."

Spain arrive at the tournament as one of the favourites, having lifted the European Championship and previously won the World Cup in 2010, but De la Fuente warned against underestimating Cape Verde in their first-ever appearance on the world stage.

"They are a very well-structured team," he said. "Physically strong, very fast, and they eliminated Cameroon. People will see tomorrow what they can do."

He suggested Spain will need to be at their best to secure a result, even with their status as favourites.

"They could be one of the surprise teams in this World Cup," he added.

Elsewhere in Group H, Saudi Arabia face Uruguay in Miami on Monday (US time) as the group begins to take shape.
