Valverde’s side have a 4-1 lead from the first leg of their tie and are favourites to progress but their coach is not getting carried away ahead of the clash at the Stadio Olimpico.
“It’s is a difficult game and we don’t know what’s going to happen,” he said.
“If [you have] 10 bad minutes, you’re out of competition. Small details can change everything and you have to avoid bad moments to stay in the competition.
”We can’t think we’ve already won. Nothing has been decided yet. It’s true we have a good avdantage, but we can’t take that for granted.
“We have to play as if it is 0-0 because anything can happen. Something could go against us, a red card. We need to go out to play well and try and win the game -- no thoughts about anything else.”

Valverde also refused to say if Sergio Busquets would be fit for the game. He said the midfielder still has “some discomfort” so it’s quite possible he may start on the bench.
