Speaking at his post-match press conference, Valverde said: “It was a complicated game, one of the worst of the year because these (cup ties) are always especially difficult.

“The team had the attitude of trying to win but it was difficult to have continuity and we lost possession because they were very strong. It was a permanent exam but I have seen quite a few good things.”

Among his changes, Valverde gave opportunities to Malcom, who has featured little since his controversial summer move from Bordeaux, Ousmane Dembele and Arturo Vidal.

A number of youngsters were also given a chance while back-up goalkeeper Jasper Cillessen impressed with some good saves.

Valverde said: “I’ve had a good look at them. They had an important responsibility.

“The youngsters are used to playing in Segunda B but today it was more complicated because Cultural played with a higher intensity.”
