Chelsea boss Jose Mourinho has no doubts about the quality of Didier Drogba.
The 36 year-old has penned a one-year deal with the Blues this season.
"For Drogba, the killer instinct is there, the technique to score goals is still there. He is still very strong physically. Mentally, exactly the same.
"Every training exercise, every competitive situation in training, his desire to compete and to win is always there. I think he's an important player for us."
