Paris Saint-Germain defender Thiago Silva knows his side must work hard to try and contain Cristiano Ronaldo.

PSG host Real Madrid at the Parc de Princes on matchday three of the Champions League on Wednesday.

Thiago Silva is aware of the threat Real pose, and singled out the club's all-time leading goalscorer Ronaldo as the player his defence must focus on.

"It's difficult to mark Ronaldo," he said. "I think he has a lot of qualities. He has all the abilities a striker can possesses.

"He’s very good with the head, the right foot, the left foot. His strike his the same whatever the feet. We need to be focused in order to mark that guy.

"We’ll try to work this afternoon in order to find the best way to mark Cristiano which is not an easy task."
