I don't think he'll be Chelsea's next captain, I mean he's turning 29 at the end of this year and he'll probably retire just a couple of seasons after JT. It's a discussion for the future, but surely it'll be Courtois.
Drogba returns to Chelsea with his original number 15 shirt, and scores the winning goal of the Champions League final in Germany with his lack kick of a ball on June 6th.
Age is simply a number, his performance is what matters. Look at JT, he's getting better with age. There's a five-foot 16 year old who's been playing in our pre-season games, kept a clean sheet each half he's played.
