Real Madrid face a tough test away in Galatasaray tonight, and manager Carlo Ancelotti will be hoping they can fare a lot better than they did in Turkey last season.
The two sides met at the quarter-final stage of the competition back in March, and although Madrid edged through 5-3 on aggregate, they did suffer defeat at Galatasaray's Ali Sami Yen stadium in the second leg.
Speaking in his pre-match press conference, Ancelotti believes it will be a difficult start to their European adventure and he will be hoping that his side can deal with the intense hostile reception his players are bound to receive.
He said: "We have a team with a lot of quality but, despite that, we are playing in a stadium where the heated atmosphere puts a lot of pressure on you and helps the team out.
"It will be a very good test for the character of our team."
Ancelotti is set to give Iker Casillas a start in goal tonight, and he added: "I have two very good goalkeepers with fantastic attitudes. Diego deserves to play in the league and Iker - because of his professionalism, reliability and competence - in the Champions League."
Meanwhile, Galatasaray striker Didier Drogba is confident that his team can spring a surprise result to get their own campaign off to the best possible start.
"The last time we played Real Madrid we beat them," said the 34-year old ex-Chelsea frontman. "I am optimistic.
"We have very strong teams in our group and we want to get out of it by playing good football. Hopefully I can score more goals."
Juventus and FC Copenhagen complete what is a tricky-looking Group C line-up that Ancelotti is charged with negotiating.
Predicted Real Madrid line-up:
Casillas; Ramos, Pepe, Nacho, Carvajal; Khedira, Modric, Ronaldo, Isco, Bale, Benzema.
