Chelsea have signed teenage Sheffield Wednesday defender Yisa Alao for an undisclosed fee on a two-and-a-half-year deal.
According to report, the Premier League has paid around £500,000 for the 17-year-old.
Liam Rosenior’s side have been in advanced talks to sign the 17-year-old for several weeks, and the deal has now been formally confirmed by both clubs. 
Alao signed a two-year contract at Stamford Bridge, valid until 2028, and he is expected to link up with Chelsea’s U21 side for the remainder of the season, rather than play a role in the first team.
The teenager made five senior appearances for Sheffield Wednesday, and he was included in the starting XI for a Championship match for the first time during the Owls’ 1-0 defeat to Portsmouth in mid-January.
In an official statement posted on the Sheffield Wednesday website, the club said: “Yisa has developed through the Owls’ academy system and was offered a professional contract. Chelsea has presented him with an excellent opportunity, and after careful consideration, Yisa has chosen to take the next step in his career…
“Yisa’s journey is a proud moment for everyone involved in the SWFC Academy – from coaches and staff to the families who support young players every day. His progress highlights the strength of the pathway at Sheffield Wednesday and its ability to help young players reach the highest levels of the game.
“As Administrators, our responsibility is to act in the best long-term interests of Sheffield Wednesday and its creditors. This transfer balances immediate value for the club with protection for the future, should Yisa’s career develop as we all hope.
“We would like to thank Yisa for his commitment and professionalism during his time at Hillsborough, and wish him every success in the next chapter of his career.”
