Real Madrid star Ronaldo: I feel no pressure ahead of Barcelona Copa tie
Ronaldo was jeered by his own fans the last time Real faced Barca and is under pressure to perform on Wednesday.
But he declared in DT: "I try to stay positive and stay secure within myself all the time. Every time I see a new challenge I always try to do a better effort than the last.
"My mental strength is very important to me.
"Before the games I relax, the pressure cannot get to me."
