Shakhtar Donetsk face the prospect of having to cash in on Douglas Costa in the coming weeks.
Shakhtar coach Mircea Lucecu concedes: "Nothing official has been done yet, but I'd prefer to keep him in the squad because he is young, only 20 years old, and had a great start to his time with us.
"We'll be playing in the Champions League and he has a group of Brazilians in Donetsk with him.
"However, if I am put in a position to sell, then there's nothing I can do about it. I won't keep players who do not want to be here, but Douglas Costa is certainly a great talent."
