Fikayo Tomori has joined Brighton & Hove Albion on loan until the end of the season.
Tomori moves to the AMEX Stadium for his first spell away from Stamford Bridge.
The 19-year-old, who can play in central defence or at right-back, was part of the Academy teams of Chelsea which won the FA Youth Cup and UEFA Youth League in both 2014/15 and 2015/16.
Tomori also won the Chelsea Academy Player of the Year award last season following a string of impressive performances, making his debut for the first team on the final day of last season in a 1-1 draw against Leicester City.
He was born in Canada to Nigerian Parents, which makes him eligible for Nigeria and Canada, but he can also play for England where he was brought up. So far he has represented Canada and England at youth level which means he can still represent Nigeria.
His new team Brighton are currently second in the Championship, just one point behind leaders Newcastle United.
