Sunderland first team coach Robbie Stockdale has insisted to the Chronicle that there is loads more to come from Duncan Watmore.
Watmore is regarded as one of the most exciting talents breaking through at the Stadium of Light, and he has been handed plenty of opportunities under Sam Allardyce.
Watmore made 25 Premier League appearances last season, and he hit the back of the net on four occasions.
The England youth international was rewarded for his fine form, with the Black Cats handing him a new contract, which will keep him on Wearside until 2020.
And Stockdale said: “He is now what looks like a Premier League footballer.
“There’s loads still to come from him, he’s in no way the finished article yet.
“But it shows what hard work and determination can do. He’s somebody who’s grasped the opportunity and taken it forward.”
Watmore has been used in a range of roles by Allardyce, with his versatility proving to be an asset.
The youngster is capable of playing out wide, up-front and he was even utilised as a box-to-box midfielder towards the end of the campaign.
Watmore is one of a number of exciting youngsters currently breaking through at Sunderland, with Jordan Pickford also involved with the senior squad last term.
Allardyce has already expressed a desire to help Sunderland start producing more home grown talent, as they have not developed many players from their under-21 side in recent times.
