Bayer Leverkusen are in talks to sign Arsenal midfielder Granit Xhaka, sources have told ESPN.

The 30-year-old has a year remaining on his current contract and although the Gunners have an option to extend by a further year, sources say the club are yet to trigger the clause.

That has created uncertainty in the midfielder's mind over his future and Leverkusen have looked to capitalise by approaching the Gunners with an offer believed to be in the region of €15 million.
