Drogba wanted to stay at Marseille for a long time.
Drogba told Canal+: “To be honest, I didn’t want to leave Marseille, and staying there on the long-term was my project.
“But a coach took the time to speak to me and made me understand that to become one of the best strikers in the world, I had to sign with Chelsea.
“This man is Jose Mourinho, a man I have a fantastic relationship with, on and off the pitch.
“He made me understand that refusing to join Chelsea would have been like a lack of ambition, while staying with my club would have been a proof of fidelity.”
