West Ham United have been offered the opportunity to sign defensive midfielder Jan Kirchhoff on a free transfer.

The 27-year-old defensive midfielder has been out of the game since leaving relegated Sunderland on a free transfer last summer after his 18-month contract expired at the end of the 2016/17 campaign.However having recovered from a succession of potentially career-threatening injuries injuries, Kirchhoff is seeking a new club - which has led to his services being offered to West Ham during the last 24 hours.Born in Frankfurt, he began his career with Mainz before joining Bayern Munich in 2013. However after just seven appearances for the German giants and a spell on loan at Schalke, Kirchhoff completed a cut-price move to Sunderland for just ?750,000 after cathing the eye of then-Black Cats boss Sam Allardyce.Despite earning positive reviews at the Stadium of Light, the midfielder's career at the club was wrecked by a serious knee cartilage injury that required surgery in December 2016 - since when he hasn't played a single competitive match.In all, Kirchhoff made a total of just 23 appearances for the Championship club. However he could be the perfect fit for Hammers boss David Moyes, who knows the player well from their time together in the North East.
