Barcelona head coach Ernesto Valverde has made it clear that his players head into their Copa del Rey quarter-final second leg against Sevilla with the attitude of looking to overturn the two-goal deficit.

The former Athletic Club tactician was adamant that his side's main priority is to qualify to the semi-finals of the competition.

"It is clear that the game [against Sevilla] is a challenge as we have 90 minutes left to turn it around," he told the press conference prior the game.

"We have to give everything.

"We are a team that, at certain times, always take a step forward and tomorrow it's our turn.

"In all the statements we make, you can see that we want to continue in the competition.

"We know that in those ties where you are behind, the fans support is fundamental, but the team is the one that engages the supporters and it's a challenge for everyone."

"We always want to win and I know that every time we don't, it's a small step back; some think it's disappointment and others view it as failure.

"If we advance or don't go through, the only certain thing is that on Saturday the sun will be there and we will have another game."

Valverde also talked about the departure of Denis Suarez to Arsenal and Ivan Rakitic's future.

"[The Denis deal] is not official yet, but it was something that all parties wanted and let's hope it goes well [for him]," he added.

"I do not think there are many more changes with regard to the squad.

"[Rakitic] is a very important player and he's been showing it since before I arrived.

"Anyway, talking about the future is a bit risky, but it's not fooling anyone to say that Ivan is very important to us."

Finally, the Spaniard spoke about the progress of Nelson Semedo, who scored the Blaugrana's first goal against Girona on Sunday.

"Nelson is a very difficult player to overlook and I played him the other day at Sevilla because of Jesus Navas and to give Jordi Alba some rest," he said.

"We are very happy with him as he is very difficult to deal with because of his speed and little by little, he improves in attack."
