Werder Bremen chief Frank Baumann admits a deal for Manchester United winger Tahith Chong is stalling.

Baumann concedes he is anxious over the club's pursuit of Chong regarding a loan deal.

He said: "There is still a lot to be clarified. I've been in business long enough to know that a transfer like this can fail because of many things.

"It has not yet been decided and there is still no final agreement between the various parties.

"But we're working on winning Tahith over so that he can play in the Werder jersey this season."
