Cristiano Ronaldo took his Champions League tally to five goals in two outings this season when he scored with two headers to help Real Madrid to a thumping 4-0 victory over FC Copenhagen in Group B on Wednesday.
Angel Di Maria also struck twice at the Bernabeu and set up Ronaldo's second goal as Real put a couple of poor performances in La Liga behind them with another emphatic display in Europe following their 6-1 drubbing of Galatasaray last month.
The home team's firepower proved too strong for a stubborn Copenhagen side who despite struggling domestically put up some stiff resistance in their first meeting with the nine-times European champions.
Portugal forward Ronaldo followed up his hat-trick in Istanbul with another sparkling display and Argentina winger Di Maria also turned in a fine performance in the absence of injured world record signing Gareth Bale.
"It was a good match," said coach Carlo Ancelotti who came under fire after Real were beaten 1-0 at home by Atletico Madrid at the weekend.
"There was some good intensity and balance at the beginning," the Italian told reporters. "We were trying to score until the final minutes and the attitude of the team was good."
Ancelotti made a few tweaks to his formation for the visit of the Danish side who held Juventus to a 1-1 draw in Copenhagen in their opening game.
Luka Modric, Sami Khedira and Asier Illarramendi were deployed in a three-man midfield, with Karim Benzema up front alongside Ronaldo and Di Maria and fullbacks Marcelo and Dani Carvajal providing width.
With their fans providing impressive encouragement high up in Real's giant arena, Copenhagen made a bright start but the hosts quickly asserted themselves and Benzema headed narrowly wide from Marcelo's left-wing cross in the sixth minute.
Just as the home supporters were starting to grow restless, Ronaldo opening the scoring in the 21st minute when goalkeeper Johan Wiland failed to deal with Marcelo's floated cross and he nodded in from a tight angle.
