Mourinho, who originally lured Drogba to Chelsea, insists the decision to re-sign the club's fourth highest scorer of all time was not clouded by sentimentality.
"Didier's coming because he's one of the best strikers in Europe," Mourinho said.
"I know his personality very well and I know if he comes back he's not protected by history or what he's done for this club previously.
"He is coming with the mentality to make more history."
