Chelsea have announced the signing of Omari Kellyman from Aston Villa in a deal worth up to £19m.
His transfer comes less than 24 hours after Villa agreed a deal with Chelsea to sign Ian Maatsen.
Kellyman, who is an attacking midfielder, has signed a six-year contract at Stamford Bridge.
The 18-year-old made only two Premier League appearances last season.
Kellyman becomes the Blues’ third signing so far this summer following English defender Tosin Adarabioyo and Brazilian winger Estevao Willian.
Willian is, however, expected to spend another season at Palmeiras before moving to England next summer.
