He said: "They are going to be very charged - after we beat Manchester United - and it will be very important for them to win against us.
"Maybe they will be a little bit aggressive towards us and I think it is going to be a difficult away game.
"They won against a big team like Liverpool, so we need to understand how they won and how well they played. It is not going to be an easy away game.
"Is it clear that we enjoyed the victory [over United]. The boys were very happy and for two days after they were smiling, but we have now archived that and we think about the next game."
