On 28 October 1998, a fresh-faced John Terry was a late substitute for Chelsea in a League Cup tie against Aston Villa.
Over the next 19 years, Terry went on to establish himself as one of the finest centre backs the world has ever seen, etching his name into history with countless fantastic performances.
Here are eight of his best moments in a Chelsea shirt.
When he first broke through at Chelsea, Terry played and learned alongside club captain and World Cup winner Marcel Desailly.
The homegrown star's first time with an armband of his own came in a Premier League game against Charlton Athletic in December 2001, and his performances earned him a role as Chelsea's vice-captain over the next few seasons.
