I like Perez the most behind a striker, and if Gouffran is up-front its fine by me. He used to be able to score goals once in a while before he got leftbackpardewed. He is not a winger by any stretch but he was brought in as a backup striker if you ask me, and with Cisse out its either him or Riviere., Shouldn't be too much of a difference, hopefully he can make some runs to make space for the more gifted players like Perez/Cabella
