He said: "There is a list. We will do what- ever is possible to please Mourinho but we have to see what the costs are. We have to wait because there are going to be long negotiations until we get to the right price.
"If there is a player to get from Chelsea, they will decide the price. It could be difficult as big players playing for big teams are more difficult to get than other players.
"It's always much better if those players want to leave. But clubs want to keep their big players."
