England's Jordan Pickford during training
The 22-year-old goalkeeper came through the youth ranks at Sunderland and went on to enjoy successful loan spells at Carlisle United, Braford City and Championship side Preston North End.
This season, the injury to Vito Mannone has seen him become the club’s number one, and his solid form has prompted a call-up to the England squad under current caretaker manager Gareth Southgate.

Pickford is widely regarded as one of the best young goalkeepers in the country, and Sunderland boss Moyes warns that the Black Cats view him as a prized asset and won’t allow him to leave in a hurry.
“The top clubs will be looking at Jordan, and I’d expect them to be. That’s what happens,” Moyes said, quoted by the Mirror.
“I don’t think we’d ever be in a hurry to sell Jordan. And if we do then we know we’ve got a big commodity, with him being a young England goalkeeper. But part of bringing players here will be that we have to sell some on the way.”

Sunderland haven’t started the Premier League season well, picking up just two points from their opening seven games as they head to fellow strugglers Stoke City this weekend.
If the Black Cats look to keep hold of their better players, they must preserve their Premier League status or risk losing them to the Premier League’s established challengers.
