Demi Mitchell has signed a new deal with Manchester United ahead of returning on-loan to Hearts.

The Daily Mail says Mitchell has penned an extended deal until 2020 at Old Trafford.

The 21-year-old spent the second half of last season at Hearts, where he impressed during his 11 appearances.

It is believed Mitchell - who can play anywhere on the left - will remain at Tyncastle until the end of the season.

He scooped the Under 23 player of the year at United last season and is highly thought of around Carrington.
