West Bromwich Albion face losing whizzkid Reiss Greenidge.
The 17-year-old centre-back caught the eye in the Under-18s last season after arriving from Arsenal.
And Chelsea scouts have been impressed with the youngster's 6ft 5in frame, with hopes his build will suit the Premier League, says the Daily Star.
The left-footed teenager has also attracted interest from four other English clubs and Hamburg in Germany.
Clubs will need to pay compensation to land the defender but the fee will be under £100,000.
