Carlo Ancelotti hailed Real Madrid's commitment and desire as they edged closer to securing the LaLiga title with a 1-0 victory at Real Sociedad.

Arda Guler scored the only goal as Los Blancos extended their lead to 14 points over second-placed Barcelona, who host Valencia in their game in hand on Monday.

The 19-year-old was making his first start since arriving from Fenerbahce, as Ancelotti rotated his squad ahead of Madrid's Champions League semi-final against Bayern Munich.

And the Italian was pleased by the character demonstrated by his players, who stretched their winning streak to six league matches.

"It was clear that everyone thought we were coming here for a walk," he told reporters. "The only ones who didn't think so were the players. They had commitment and attitude. They had the desire and enthusiasm to keep winning.

"We have a spectacular squad. They have this attitude that they feel like they have to win every game. There are four points left to clinch the LaLiga title, and we are very close."

Guler added on Realmadrid TV: "This is the best club in the world and scoring is one of the best feelings.

"This is Real Madrid, the quality of the players is incredible. We're all always ready to play, and I think we've shown that here. I'm waiting patiently, and I'm still working hard every day."

Ancelotti's rotation meant a first start in eight months for Eder Militao, who marked his return from a ruptured anterior cruciate ligament in his left knee with a clean sheet.

"I've come back to play 90 minutes and I feel like a player again after many months out," the defender said. 

"We have to keep winning, we know that nothing is won yet. We have a big advantage, but we have to keep doing a serious job until the end."
