Hummels refusing to comment further on United talk

Mats Hummels has admitted he is growing weary of talk linking him with a move from Borussia Dortmund to Manchester United.

Borussia Dortmund captain Mats Hummels is refusing to make any further comment on speculation linking him with a move to Manchester United.

The Germany international has long been regarded as one of the Premier League's club top targets and previously indicated that he would be open to leaving Dortmund last month.

Speculation over his future continues to persist, but when pressed on the topic by Bild, Hummels said: "I don't want to talk about that topic constantly.

"I did it a few weeks ago - and that must be enough."

Asked about reports of a bid from United, Dortmund sporting director Michael Zorc replied: "I can't confirm this."

Hummels has made 26 appearances this season for a Dortmund side that sits ninth in the Bundesliga having spent much of the campaign in the lower reaches of the table.
