Sunderland skipper John O'Shea can see former club Manchester United moving for Borussia Dortmund defender Mats Hummels.
Dortmund have ruled out selling their prized asset on several occasions last summer, but O'Shea has urged United to do everything they can to sign the dominating centre-back.
He said: "I could definitely recommend them Mats Hummels from Germany.
"He was fantastic last night.
"It seems to be that he doesn't want to leave Germany.
"But you never know, there's always different incentives they [Man United] can offer to change that. But he was very good last night."
