Chelsea are facing a battle to keep hold of academy star Xavier Simons amid reported interest from Brighton, Southampton, Norwich and Watford.
Simons, who left Brentford to sign for the Blues back in 2016, is one of the club's most highly-rated youth prospects and was also handed his senior debut by Thomas Tuchel this season.
The 19-year-old midfielder made his Chelsea bow in their Carabao Cup quarter-final victory away at Brentford, playing from the start in a 2-0 win over his former side.
There are high hopes for Simons at Stamford Bridge, yet Blues chiefs have a dilemma on their hands with his current contract set to expire at the end of June.
