Jeremy Mathieu is looking forward to taking on his former side, Valencia, when Barcelona visit the Mestalla on Sunday night.
"Playing against Valencia will be a special game for me," he said at a pre-match press conference.
"Valencia have changed a lot with regards to last season. They have a squad that can do great things."
Asked about what he thinks his reception would be during the game, he replied: "I don't know, we'll see. I left a good impression there and if they whistle me I have to accept it.
"I will be on the opposite side, now I'm 100% Barça, but I had great times at Valencia."
