Duncan Watmore has penned a new double-your-money deal with Sunderland.

The Mirror says Watmore has shown he is the real deal – by doubling his money at Sunderland.

The rookie forward, who led the England Under-21s to a comeback win last week, has penned a lucrative contract extension until 2020.

Watmore, who was released by Manchester United as a kid, said: “I am delighted to commit my future to Sunderland. I've had a great few years here developing my game and I hope to push on further."
