The Eibar clash is coming up this Saturday and Setien has asked the players to imagine this match as a cup final.
He told a pre-match press conference: “We’re concentrated on this game we’ve got before we face the three or four coming up which are going to be important.
“We’ve treated the game as if it were a final and we need the three points.
“Not only will that allow us to continue up there, but it will strengthen us for the games to come.
“We have to do things well, it’s not going to be an easy game.”
“We’ll surely see him starting in some game. Maybe it’s a bit early now.
“He’s come here in good shape but there are concepts and things that need explaining to him and that he needs to understand.
“We hope he will help us a lot.”
Setien added of his possible line-up this weekend: “It’s true that you need to take (the Napoli game) into account but our first priority is to win this game.
“We won’t reserve anything that will help us win this game.”
He said on Thursday: “I’m encouraged by yesterday’s training session. We did some exercises and had a game with numerical superiority and I really liked the intensity, and how we defended and attacked.
“That means I will go to Barcelona with my head high.”
