Victory for Ernesto Valverde’s side would hand Real Madrid a fourth La Liga defeat of the season already and see them move seven points clear of their rivals.
Suarez spoke about the intensity of the matches with Los Blancos and how form goes out of the window in such a big game.
“El Clasico is always El Clasico. Look at El Clasico last year, we were practically champions already but the intensity was the same as in any Clasico. It’s like that.
“You’re always up for it. You do have to look at the teams’ most recent results but the Clasico is the Clasico and nobody thinks about the other team’s morale or if they’ve been playing badly or better.
“We have to play our game, take our approach, and not worry what players will be there for the opposition, in this case Madrid without Cristiano Ronaldo.
“Obviously it’s what we want for the fans and ourselves, to stay top of the Liga. I think it’s time to win and hopefully that time is now.”

With Lionel Messi missing due to injury there will be added pressure on Suarez to supply the goals on Sunday.
The Uruguayan has a pretty good Clasico record, with six goals in his last 10 outings against Real Madrid.
