Dembele is one of the many Barcelona players at the centre of much media attention lately, with it even being suggested that the Frenchman could have played his last game for the club unless he agrees to sign a renewed contract.

"We need him, he's shown a good attitude.
"He'll be an important player for us and he's part of the squad."
