Sunderland signed Billy Knott to an apprentice contract in the early stages of the 2010-11 season after the player's release from Chelsea.
A creative winger who can also play in the middle, Knott was originally on the books at West Ham United before joining Chelsea as 14-year-old.
Knott, who has represented England at under-16 and under-17 level, then left Stamford Bridge before being signed on at the Academy of Light.
He made a good start to life in Sunderland's under-18 team, scoring five goals in his first eight games.
And Knott's form caught the eye of manager Steve Bruce, leading to him being called into the first team squad for the first time in late February 2011.
He didn't manage to see any playing time but will be hoping to make a splash in 2011-12.
