Drogba will take the field at Stamford Bridge for the first time since leaving the Blues in the summer of 2012, immediately after scoring the winning penalty to clinch the club's first Champions League triumph.
When asked whether he could see Drogba coming back, the Portuguese told reporters: "That's not for me [to decide]. That's for Chelsea [to decide]. I think it has to happen one day."
"When? I don't know. As a player, as a coach, as an ambassador? Next year, in four to five years, in 10 years? I don't know. But when a person represents so much to a club and when a club represents so much to a person I think he has to be welcomed back." Mourinho continued. "Undoubtedly he's one of the most important players of the history of this club. That's not a doubt.
"All Chelsea supporters agree with that. We don't say the most important one because that's not fair for other people that was in the same level and in the same generation.
"Is he the same player at 36 than he was at 26? I think nobody is, but he is one of the best strikers in the world. That's for sure."
