Drogba left Chelsea for Shanghai Shenhua in the summer of 2012 after helping the Blues to win their first ever Champions League trophy in Munich.
Following a short stint in China, the Ivorian left for Turkey and Galatasaray, where he currently plays under former-Manchester City boss Roberto Mancini.
Drogba returns to Stamford Bridge for the first-time to play tonight, as Chelsea face Galatasaray in the second leg of their Champions League last-16 match.
And Drogba has admitted he would have liked to have still been playing for the Premier League club, but the player and team could not agree terms on a new contract.
“Why did I leave Chelsea? I didn’t want to talk about that, but I would have stayed if we could find a satisfactory agreement for both parties,” Drogba told French newspaper L’Equipe.
It’s speculation, but Chelsea do not offer more than one-year deals for players over the age of 30 - so perhaps Drogba wanted a longer-term contract than Chelsea were willing to sanction.
Other than that, the disagreement more than likely centred on pay.
The 36-year-old will be a free agent again in the summer if he doesn’t extend his Galatasaray contract, and he admitted a return to London is appealing.
“I will live there at the end of my career,” Drogba continued. “My children grew up there and like London.
“I remember at the start I was depressed there, seeing dark sky and night so early every day. The two first seasons I was always saying: I am fed up, I can't adapt, I want to leave! Finally I held on and there is the result!"
