As Spain gear up for their first game in the 2018 World Cup, against Portugal, goalkeeper David de Gea has revealed that La Roja have done their homework well and studied forward Cristiano Ronaldo.

The Manchester United star didn’t have the best of games against Switzerland during the build-up to the tournament, but is hoping to kick-start his World Cup campaign on a positive note.

“The first match is always important, and more so when it is against a rival as hard and complicated as Portugal,” he continued.

“We have to face the game as we did in the qualifying phase, that is, playing our own game.

“Cristiano Ronaldo is well studied, and everyone knows he’s one of the best in the world.

“He also has a great team behind him, they’re European champions and it will be a tough game.”
