The Real Madrid boss insists the player has moved on from whistles he received from the crowd at the weekend and believes Robert Lewandowski's absence this week will be key
The Portugal international was jeered by the Madrid fans after he refused to set up a team-mate during Saturday's 5-0 win, despite having earlier opened the scoring before setting up Dani Carvajal with an unselfish pass.
Ancelotti has made it clear that nothing more should be made of the incident and says Ronaldo is fired up for the Champions League quarter-final clash with Borussia Dortmund.
"I see Cristiano [Ronaldo] as being highly motivated," Ancelotti stated at a press conference.
"The whistles he received from the crowd have now been forgotten. He was whistled because he didn't pass the ball when that was perhaps the best option. That's all there's to it.
"Cristiano is always giving his all for the club, for the team and for everyone."
Robert Lewandowski - who bagged four goals in Madrid's semi-final defeat to Dortmund last season - is suspended for the first leg, and Ancelotti admits his loss could be crucial.
"Dortmund are missing Lewandowski which is a big loss for them," he said.
"They are a compact team and have excellent transitions in their play [from defence to attack]. They have injuries but won’t change their style.
"I admire their coach a lot. He has done a fantastic job there. He got to the final of the Champions League last season which is a big objective for any coach."
Ancelotti also reflected on last year's semi-final tie and stressed that the Spanish giants will need to play with a lot of intensity in order to match their opponents this year.
"I watched the games against Dortmund from last season. They were strange matches.
"I thought that in the first leg Madrid had good control in the first half. The second half was incredible. In the Champions League things like that can happen. We will need to play with a lot of intensity."
