This quiz will really test your memory of Chelsea players over the last few years.
Back on 28 October 1998, a young John Terry made his Blues debut - coming on as a late substitute in a League Cup tie against Aston Villa.
Since then, the centre back has had a whole host of teammates in a Chelsea shirt.
