jose Mourinho believes veteran striker Didier Drogba will still strike fear into defenders when he begins his second spell at Chelsea.
"The killer instinct is still there," Mourinho said of the 36-year-old who signed a 12-month contract last month after spells in China and at Turkish club Galatasaray since leaving Stamford Bridge following the Champions League final victory in 2012.
Drogba will give Mourinho a tried and tested formula in attack, where he will be vying for a place with Spanish duo Fernando Torres and new signing Diego Costa.
"He still has the technique to score goals and the physical strength and presence is still the same," added Mourinho, who signed Drogba from Marseilles in 2004.
"Mentally, he is the same. Every training exercise, his desire to compete and to win is always there. He will be an important player for us."
Drogba scored 157 goals for the club and won three Premier League titles as well as the FA Cup four times and the League Cup twice.
