Chelsea are closing in on signing attacking midfielder Omari Kellyman from Aston Villa for a reported £19m.
The deal is in the process of being done, with personal terms and a medical needing to be sorted.
Discussions are under way for a five or six-year contract, with the 18-year-old expected to be part of Enzo Maresca's first team squad.
The highly-rated youngster has made six first-team appearances at Villa Park and is an England Under-19 international.
Villa have also agreed to buy defender Ian Maatsen from Chelsea for £37.5m this week - as both clubs remain conscious of the Premier League profit and sustainability regulations before and after the 30 June accounting deadline.
