Chelsea have announced the transfer of Sheffield Wednesday's left-back, Yisa Alao.
Idman.Biz reports, citing the club's official website, that the 17-year-old has signed a contract with the Blues until 2028.
Alao came through the Sheffield Wednesday academy and made his debut for the Owls' first team last August. Since then, he has made four more appearances, including starting in the recent FA Cup game against Brentford and the Championship match against Portsmouth.
The deal is worth approximately £500,000 (€575,000). However, if all conditions are met, the deal could exceed £1 million (€1.15 million).
After 23 games, the London club is fifth in the league table with 37 points. The gap with the leader, Arsenal, is 13 points.
