Ronaldo struck either side of Gareth Bale’s strike 28 seconds into the second half, while Benzema recovered from an abject start to the match by assisting Los Blancos’ first two goals.
Having heard his team-mate jeered earlier in the contest, the Portugal international then selflessly let Benzema convert an 89th-minute penalty after Victor Laguardia brought down a marauding Bale.
The result means Madrid have won five consecutive matches in all competitions for the first time this season and Zidane will draw particular encouragement from his headline attacking stars operating so brilliantly in tandem.
A fourth consecutive LaLiga victory was ultimately too much to ask for a resurgent Alaves, who showed plenty more of the their encouraging form under Abelardo before being outgunned, Galactico-style.
Karim Benzema turned jeers into cheers as Cristiano Ronaldo and Gareth Bale also starred on a fine outing for Madrid’s ‘BBC’ against Alaves.
Cristiano Ronaldo passed up the chance to complete a hat-trick and allowed Karim Benzema to complete a 4-0 win over Alaves with a late penalty as Real Madrid’s ‘BBC’ reunited to fine effect.
Madrid began slicing Alaves open at will and it was a surprise of sorts that it took until the 61st minute for goal number three to arrive.
Bale swept a pass out to Lucas Vazquez on the right and Ronaldo timed his run perfectly to convert the Spain winger’s low cross for his 28th goal of the season.
Lucas thrashed into the side-netting chasing and was again denied the goal his efforts deserved 15 minutes from time, this time by the impressive Pacheco.
