Borussia Dortmund are willing to part with Manchester United and Arsenal target Ilkay Gundogan in the January transfer window, with the German international refusing to sign a new deal with the German giants.

The midfield wizard has recently returned from a long term injury, and was thought to be an integral part of Dortmund’s attempt to avoid relegation this season, with the Bundesliga side having slipped down the table in surprise fashion since the campaign kicked off.

Reports in Germany suggest that the club are willing to move Gundogan on after he refused to agree to a new contract, according to the Daily Express.

This is a particular issue for the Prussian side, who have seen the likes of Robert Lewandowski leave on free transfers in recent seasons.

While Man Utd are thought to be favourites to capture him, they will likely face competition from Arsenal, who are also keen on his signature.

Gundogan has previously been valued at around £20 million by Real Madrid, who are also thought to be interested.
