Roberto Mancini has urged Didier Drogba and Wesley Sneijder to lead Galatasaray to a Champions League shock over their former manager Jose Mourinho.
The Turkish giants host Chelsea in the first leg of their last-16 tie on Wednesday and their big-name stars will be coming up against a familiar face.
Drogba famously starred in two title-winning Mourinho teams at Stamford Bridge, while Sneijder was a key component of the Inter Milan team which he guided to an historic treble in 2010.
However, Mancini expects them to put old friendships to one side in Istanbul.
"Didier was an important man and an important player for Chelsea," Mancini told reporters.
"Wesley won the Champions League under Mourinho. I think they have a good relationship but tomorrow for 90 minutes I think they will be enemies.
"After that they can go and have dinner together. But for 90 minutes I think they will play not 100 per cent, but more because we need Wesley and Didier to play very well tomorrow."
Drogba scored 157 goals for the Blues during an eight-year spell which ended when he moved to Galatasaray in 2012.
