Chelsea have had an offer for West Brom teenager Isaiah Brown rejected.
Brown, 16, has made just one senior appearance for the Baggies but has been capped for England at youth level.
The midfielder is evidently held in high regard by Jose Mourinho and Chelsea, but West Brom insist they are not looking to sell their academy product.
"Albion have today rejected an offer from Chelsea for academy product Isaiah Brown," a club statement read.
"Under Premier League rules the Baggies are due compensation from the London club for the 16-year-old midfielder, who has been at the Hawthorns for three years and had agreed to sign scholarship forms."
Albion sporting and technical director Richard Garlick added: "We are disappointed by Chelsea's offer.
"We have invested a lot of time and money in Isaiah's development as a player and - as one of our most exciting academy products in recent years - we had hoped to bring him through into our first team.
"But Chelsea have forced our hands and we are more than prepared for the matter to be decided by a tribunal if needs be.
"More importantly, it makes you question why these young players are joining bigger clubs when they are likely to gain more first-team opportunities in the Barclays Premier League at clubs similar to us."
