Our latest addition to the defensive ranks has come a long way since first joining Manchester City more than 20 years ago.
Tosin Adarabioyo was born just three miles from Stamford Bridge but after moving north, first joined City as a five-year-old and worked his way through the ranks before going on to become a professional.
Loan spells at West Bromwich Albion and Blackburn Rovers proved crucial to his development before signing for Fulham in 2020.
Since then, the 26-year-old has gone on to become one of the most consistent defenders in the Premier League and is set to join Chelsea on July 1 when his current contract expires.
Let's take a look at some of the best snaps from Tosin's career so far.
