Arsenal boss Mikel Arteta is delighted with the training ground approach of David Luiz.

While the 32-year-old has twice been overlooked for the captaincy since joining, his influence in the dressing room and on the pitch has grown steadily during the campaign.

And Arteta has called on his Arsenal players to learn from Luiz's attitude in training and his recently improved performances as they prepare for Saturday's trip to Crystal Palace.

Acknowledging that Luiz was becoming something of a mentor to Arsenal's young players, Arteta said: "Yes, that's what I wanted to demand of him.

"He is a player that has won more trophies than anybody else in that dressing room.

“We have to use that in a very powerful way. I wanted him to step up, I wanted him to put all his qualities - his personality and his experience - towards the team and he made a big step forward.

“I am very, very pleased with him. Is he becoming more consistent? I hope so. In the games he has played under me so far, he has been terrific.

“His attitude in training, the way he communicates with his team-mates, his desire to still learn, it's superb. I am delighted with him."
