Chelsea have confirmed the signing of Carney Chukwuemeka from Aston Villa for an undisclosed fee.
The 18-year-old midfielder, who was part of the England side that won the Under-19 European Championship this summer, moves to Stamford Bridge having decided against signing an extension to his Villa contract, which was due to expire next summer.
Villa boss Steven Gerrard left the midfielder out of the club's pre-season tour of Australia and he had been training with the under-23s. Gerrard was understood to have put a £20million price tag on the player.
Chukwuemeka, who turns 19 in October, made his first-team debut in May 2021 and last season made 14 appearances but just two of them were Premier League starts.
He said of his switch to Stamford Bridge: "It’s been quite hectic but I couldn’t get Chelsea out of my head the last few days so I’m just happy and relieved that it’s all done.
"I’m so excited and just can’t wait to get on the pitch, meet all the players and try to win games and trophies with Chelsea."
Chairman Todd Boehly added on the club’s official website: "Carney is one of the most exciting young players in Europe so we are really looking forward to seeing him in action at Stamford Bridge.
"We are delighted to be able to bring him to Chelsea and add such a talented young individual to our squad for the new season and beyond."
A brief Villa statement read: "Aston Villa can confirm Carney Chukwuemeka has completed his transfer to Chelsea.
"Everyone at the club would like to wish Carney all the very best for the future."
Cesar Azpilicueta has committed his future to Chelsea by extending his Blues contract until 2024.
The club captain has added another two years to his west London stay, thwarting Barcelona's long-running pursuit of the 32-year-old.
The Spain full-back joined Chelsea from Marseille in 2012 and has swept the board of major club trophies since, with the 2021 Champions League and 2022 Club World Cup completing the set.
Manchester United left-back Alex Telles has completed a season-long loan switch to Sevilla.
The 29-year-old joined the Old Trafford giants from Porto in October 2020 and made 50 appearances in all competitions for the Red Devils.
Telles has mostly played back-up to Luke Shaw and was pushed further down the pecking order by the summer arrival of Feyenoord's Tyrell Malacia.
Brandon Williams has also returned to the club after spending last season at Norwich and Telles has joined Sevilla on loan for the 2022-23 campaign.
The PA news agency understands the La Liga side are covering his wages in full and that the deal does not include an option or obligation to sign the Brazil international.
