Sunderland are set to bolster their defensive options with the signing of Bayern Munich defender Jan Kirchoff, according to Fichajes.

Sam Allardyce has revealed he will enter the transfer market this January, with the Black Cats boss also confirming signings will be made from outside the UK.

And now reports suggest the North East club are closing in on a deal to bring Kirchoff to the Stadium of Light.

The 25-year-old, despite being signed by Bayern in 2013, has spent a large amount of time on loan at Bundesliga club Schalke 04, although he has featured once under Pep Guardiola in the German Cup.
