Wolfsburg attacker Andre Schurrle expects Jose Mourinho to transform Manchester United's squad.

Schurrle played for Mourinho at Chelsea.

He reckons that won't be the end of the spending – and predicts that the Special One could cause friction with his no-nonsense methods.

Schurrle said: “It's difficult. He expects a lot of his players. He will probably buy a lot players that suit him and how he wants to play and we will see how they get on.

“If you do what he wants and play well, it's easy. But sometimes he wants a lot of you and it's difficult. He is a very demanding manager."
