England Under-21 goalkeeper Jordan Pickford has signed a new long-term deal with Sunderland.
Pickford made his Sunderland debut in the 3-1 FA Cup defeat by Arsenal on January 9 and has since made his first Premier League start, featuring in the 4-1 reverse against Tottenham at White Hart Lane.
The 21-year-old has been with Sunderland since the age of eight and his new contract commits him to the club until the summer of 2020.
Manager Sam Allardyce told the club's website: "Jordan is an exceptional talent who has already demonstrated he is comfortable playing at the highest level.
"At the tender age of just 21, which is still very young in goalkeeping terms, there is still a lot more potential for development which is really exciting for us.
"It's always great to see a local lad progress through the academy ranks especially for our fans, and I am certain that Jordan has a very bright future ahead of him here at Sunderland."
Pickford has also spent time out on loan at Darlington, Alfreton Town, Burton Albion, Carlisle United and Preston North End.
