Joselu reduced the deficit with a header just prior to the hour mark before Benzema struck his second in the 70th minute.

It was a first win in four games in all competitions for Real, whose boss Zinedine Zidane was absent from the contest after testing positive for coronavirus.

The result leaves the second-placed defending champions – now unbeaten in nine league outings – four points behind Atletico Madrid, having played two games more. Atletico are in action on Sunday, hosting Valencia.

Alaves made a bright start, with Joselu and Martin Aguirregabiria seeing efforts go off target before Benzema had a shot blocked at the other end.

Casemiro – one of only two survivors in the Real starting line-up from the Alcoyano match – then put the visitors in front, heading past Fernando Pacheco as he connected with a Toni Kroos corner.

Hazard went close with a shot around the half-hour, then produced a clever flick to set up Benzema's goal towards the end of the half.

The Belgian subsequently netted the third soon after, latching on to Kroos' pass and sending a finish beyond Pacheco.

Alaves made another strong start after the break and after Joselu had brought a good save out of Thibaut Courtois, he beat him with a header from Lucas Perez's corner.

Real, though, restored their three-goal cushion as Benzema cut into the box from the left and fired a low strike into the corner of the net.
