The Portugal international believes he and his boss can provide a winning combination in Europe, as they aim to stop Barcelona's dominance on every levelReal Madrid forward Cristiano Ronaldo believes Jose Mourinho "is the best coach in the world".
And he hopes the coach's tutelage, in his second season at the club after joining from Inter last year, will help his side reach the summit of the European stage.
It was Clasico rivals Barcelona who kicked the ladder from under Madrid in last season's competition as hopes of glory were razed to the ground in the semi-finals.
However, Ronaldo feels it will be different this season.
"Mourinho is currently the best coach in the world and it's fantastic to work with him," Ronaldo told the club's official website.
"Mourinho is first my friend, then he’s my coach and finally he’s the person I’m really happy to be associated with."
Madrid play Getafe this weekend, but all eyes are on next week's Champions League opener against Dinamo Zagreb.
"Away games are always the hardest, so we want to prepare well to avoid surprises," he said.
"We don’t have a minimum objective this season. We’ll try to do our best and win the Champions League."
Kick-off against Getafe is at 20:00 (CET) on Saturday as the Spanish giants look to continue their stellar form after beating Real Zaragoza 6-0 in their last league clash.
