Chelsea have revealed Romeo Lavia squad number after complet his signing from Southampton for a reported fee of £60m.
The Belgium star has signed a seven-year contract at Stamford Bridge through 2030.
Lavia had strong interest from Liverpool but, like Caicedo, opted to move to west London over Anfield.
Chelsea first bid for the player only weeks after his move from Manchester City to Southampton last summer and co-director of recruitment and talent Joe Shields is thought to have played an instrumental role in the deal.

Shields brought Lavia to the south coast upon leaving City last year and has since taken up a role at Chelsea alongside co-sporting directors Laurence Stewart and Paul Winstanley.
Former Anderlecht youngster Lavia, who has one senior international cap for Belgium to his name so far, will wear the No45 shirt at Chelsea this season, previously held by the likes of Nathaniel Chalobah and Fabio Borini.
It is the same number that he had at Southampton, where he made 34 appearances across all competitions last term as the Saints were relegated from the Premier League.
Lavia joins a Chelsea midfield that features Caicedo, who signed for a British-record fee of £115m, and Enzo Fernandez, who signed for £106.8m earlier this year.
