"We have been talking with the players and clearly we need to forget about that game and think about Marseille. This is a different team in a different competition and it will be difficult," he said.
"Obviously we have taken confidence from it but it's important not to think about other games, just this one.
"Marseille are a good side and I think they are stronger than when we met them last season. I heard people saying they weren't as good, but in terms of the team I think they are better. They are well organised, they know what to do and they can change systems.
"We know we are playing well but the Champions League is different so we will have to see."
