UPDATED 11:47 24th January 2017
Fikayo Tomori arrived on loan at Brighton & Hove Albion on loan in January 2017 until the end of the current season.
Tomori has represented Canada and England at youth level, and is eligible to play international football for Nigeria, through his parents.
He has been with Chelsea since the age of eight, and made his debut for the club's first-team in their final match of last season against champions Leicester City at Stamford Bridge.
Tomori has been a regular in Chelsea's under-23s over the past two seasons, and helped the club win back-to-back FA Youth Cups and successive Uefa Youth League Finals in 2015 and 2016.
He was also named in the Uefa European Team of the Tournament last summer, after an impressive campaign with England's under-19s.
