"The football I saw was very good, I saw a lot of incredible things - but Istanbul is a difficult place to play and they have players with a lot of experience, with great character and personality.
"They will fight hard against us, but we will take it very seriously, its the only way to get through."
In the night's other game, Malaga escaped with a goalless draw at La Rosaleda after holding Borussia Dortmund.
The Spanish club, which is making its debut in the Champions League, extended its unbeaten home record in European competition to 14 matches.
But it could have been quite different had the Germans not wasted a whole host of chances with Mario Gotze and Robert Lewandowski both failing to convert opportunities.
And it was almost punished when Isco's rasping drive forced Dortmund keeper Roman Weidenfeller into an impressive stop.
"It's a positive result because if we score there it will make it difficult for them," Malaga winger Joaquin told Canal Plus.
"We have the same chance as they do of going through and we'll try to repeat what we did tonight, playing a serious game and trying to grab the odd goal," he added.
"We came up against what we were expecting, which was a great team that plays football very well but we also had our chances. They made us suffer but we were expecting that."
Dortmund coach Jurgen Klopp insists he is more than happy with his side's position going into next week's second leg.
He told reporters: "I can live with this 0-0. We did everything well from the first kick to the final whistle but it's a higher level.
"We know what we have to do in the return match."
