Barcelona head coach Ernesto Valverde urges his players not to believe that they have already won a ticket to the Champions League semi-final.

In the first leg of the quarterfinals, Barcelona beat Roma 4: 1.

"Tomorrow Roma will try to play even more intensively. When you have to catch up, you should try to score first. I can assume that they will go on the field for this purpose, and we should be alert here, "said Valverde.

"I always admit the idea that we can lose. But in the same way, I always think that we can win. We know that in terms of counting we have a great advantage, but Roma has good players. We must be prepared for this ".

"We can not think that we have already won. In the first match we got an excellent result, but we have to play, as if still 0: 0. We need to play for victory and not think about anything else ".

"I've been in football for a very long time and I know that incredible things can happen here. We must make sure that nothing improbable happens tomorrow night.. You can not go on the field with the idea that Roma is not an opponent for us. Self-confidence can come out sideways ".

The return match of the 1/4 finals of the Champions League between Roma and Barcelona will be held on Tuesday, April 10th. The beginning of the meeting at 21:45 Kiev time.
