Sevilla defender Aleix Vidal insists his side must be ‘totally concentrated for the entire game’ against his former club Barcelona on Saturday.
The wing-back returns to the Camp Nou for the first time since his summer exit, while Los Rojiblancos sit one point clear of Barca at the top of La Liga.
“Of course, it is a difficult match but the same number of points are on offer,” Vidal told Sevilla club media.
“As a visiting player at the Camp Nou it is always extremely difficult because you need to concentrate totally for the entire game because at any moment they can change the game.
“They have a level of player which is at the elite of football and it is strange when a team like that does not win their games.
“But we go to compete, and we believe in our ability to achieve a positive result, but we must be aware of what we face.
“All the players are focused on the match, we are preparing thoroughly and with players returning from international duty we are now more cohesive.”
