Chelsea manager Jose Mourinho has challenged the club's supporters to produce just 10% of the atmosphere generated by Galatasaray fans when the two sides lock horns again at Stamford Bridge.
The Blues were met by a predictably hostile crowd in Turkey, where they scored a precious away goal early on through Fernando Torres.
Galatasaray, featuring former Chelsea favourite Didier Drogba and ex-Inter star under Mourinho, Wesley Sneijder, managed to pull a goal back in the second-half which leaves the tie nicely poised for the return leg.
Mourinho and midfielder Frank Lampard said after the game that Galatasaray's supporters played a huge role in helping their team fight back from a one goal deficit.
Speaking to Sky Sports afterwards, Mourinho said:
"If Stamford Bridge can give us 10 per cent of what this public gave them, it would be fantastic for us.
"I just ask 10 per cent of what this stadium gave to Galatasaray. And we have to try and go through but the second leg will be difficult.”
Fernando Torres gave Chelsea 9th minute lead in Turkey after rounding off a slick move, but the Premier League side were denied victory in the second period after conceding a sloppy goal from a corner kick.
