Chelsea, Barcelona and Bayern Munich want Rangers 15-year-old midfielder Billy Gilmour, according to The Sun.
The teenager has caught the eye playing for the Glasgow side and Scotland, and is being ear-marked as a big playmaker talent for the future.
FIFA rules prohibit them making a move until the Ayrshire schoolboy turns 16 on June 11 next year.
Scouts from Barcelona, Bayern Munich and a clutch of English clubs watched him impress for Scotland in the Victory Shield earlier this season.
FIFA rules mean any club could land Gilmour for as little as £100,000 in cross-border compensation.
Gilmour is under contract at Rangers until the end of the season, but according to ESPN Chelsea have already offered the Scottish club £500,000 to sign the player now rather than wait until he is 16 and try and land him on a compensation fee.
