Sheffield United ace Sander Berge has been warned about his future with the Premier League to begin.

The Blades have told the star midfielder that he must renew his contract if he wants to play.

Berge, per The Mail, is not eager to sign an extension with the Blades as he wants a move to Burnley.

The 25-year-old has been told he must renew, finalise a move in the coming days, or sit on the sidelines when the Premier League begins.

A move to Burnley could be completed, with the Clarets said to be offering around £12 million.

The transfer would be a blow for the Blades, as Berge was impressive during their promotion run last season.
