Mourinho may know us but we know Mourinho says Wesley Sneıjder
Wesley Sneijder does not believe Chelsea will have the upper hand in the Champions League quarter-finals due to Jose Mourinho knowing the team well.
"First Chelsea is a great side, everybody has to accept that," Sneijder said.
"Mourinho knows us well and that is an advantage but the same applies for us, we know Mourinho very well perhaps better than the Chelsea players know us.
"If we show the same spirit we did against Juventus we could achieve another big result."
Mourinho has worked with Galatasaray players Sneijder, Didier Drogba and Hamit Altintop in the past.
The Portuguese manager also faced Galatasaray last season in the quarter-finals of the Champions League as manager of Real Madrid.
Real defeated Galatasaray 5-3 on aggregate and progressed onto the semi-finals.
Galatasaray's Match Day 6 Champions League group game against Juventus was abandoned due to heavy snowfall and hail.
Sneijder scored the winning goal against Juventus on Champions League Match Day 6 to take Galatasaray into the Last 16.
Galatasaray will face the Blues on Wednesday 26 February and the return leg will be held in Stamford Bridge on Tuesday 18 March.
