Chelsea have announced that Academy attacker Alex Kiwomya has left the club to join Doncaster Rovers.
The youngster spent last season on loan at Doncaster and helped them earn promotion from League Two.
He never made his debut for Chelsea's first team but was part of the squad that won the FA Youth Cup and UEFA Youth League.
After signing the contract he said: "I know the club came in for me a couple of times last season, but we could not get the deal done.
"It is nice to know they have had their eye on me for a while.
"It was a hard decision to leave Chelsea as I have been there from the age of 14, but I think it was the right time to make a permanent move and show people what I can do."
A statement on the Blues website reads: "The transfer of Chelsea Academy attacker Alex Kiwomya to Doncaster Rovers has been agreed.
The 21-year-old, who was an FA Youth Cup and UEFA Youth League winner with Chelsea, will become a Doncaster player on 2 July."
