Manchester United are watching Leon Goretzka's situation at Schalke.

The Germany midfielder is off contract in June and currently running down his deal.

Sky Sports says United are interested in signing Goretzka.

Schalke want him to stay and have offered him a new deal which would make him the highest paid player in the club's history.

Goretzka joined the Gelsenkirchen-based club in 2013 from Bochum and has flourished since, becoming one of the brightest talents in German football and able to fill in a number of midfield roles, both central and wide.
