Sunderland realise the need to add defensive quality to their squad in January.
Sam Allardyce is eager to strengthen the Black Cats’ squad at the next opportunity, and signing a central-defender is one of his most urgent priorities.
Sunderland have struggled defensively this season, and Allardyce realises that he needs to make additions to have any chance of keeping the Wearsiders in the Premier League.
Kirchhoff is reportedly at the top of his wishlist, as the 25-year-old could be available at a bargain price.
Kirchhoff’s contract at the Bayern expires at the end of the season, and there are no suggestions that the German giants will offer him a new deal.
The former German youth international has made just one appearance for Pep Guardiola’s side this campaign in the German Cup.
If Kirchhoff does move to Sunderland he will compete with the likes of John O’Shea, Younes Kaboul and Sebastian Coates for a place in their defence.
