Chelsea have reached an agreement to sign Belgium midfielder Romeo Lavia from Southampton, according to media reports on Tuesday.
The BBC reported that Chelsea agreed a fee of £53m for the 19-year-old.
Lavia signed for Manchester City in 2020 but made just two appearances for the club before joining Saints in July 2022 for £10.5m.
The defensive midfielder played 34 games in all competitions for the south-coast club, scoring once but was unable to prevent Southampton's relegation from the Premier League.
Liverpool also made a bid for Lavia but missed out on the Belgian who will now join Chelsea's British record-signing Moises Caicedo at Stamford Bridge.
