Cristiano Ronaldo insists Real Madrid's quest for La Decima got off to the perfect possible start with a 6-1 rout of Galatasaray on Tuesday.
The 28-year-old scored a hat-trick for Los Blancos, with Isco's goal and a Karim Benzema brace rounding out the win.
Real moved to outright first in Group B after Juventus' draw with FC Copenhagen and Ronaldo believes the away result was crucial in giving his side a confidence boost to start their campaign.
"Things couldn't have started better for us," he said. "Scoring six goals is really good and will give us a lot of confidence. We wanted to start well against a good team who showed their ability in the first 20 minutes, they created chances."
Meanwhile, coach Carlo Ancelotti has played down Iker Casillas' rib injury and expects the goalkeeper to be available for selection ahead of Sunday's La Liga clash with Getafe.
"It was a good game," Ancelotti said. "The result was fantastic. We suffered a little during the first half. But after Isco's goal the game became a little easier for us.
"It's good for us to improve our confidence. It is not an easy stadium to play at where the pressure is so high. Hopefully Iker will be back with us in three or four days."
