Nacho Monreal has embraced the opportunity to take on a leadership role this season.
Unai Emery has said he'd like from three to five players in his captaincy group and Monreal is ready to step up.
"To be one of the captains makes me happy and makes me feel like I have more responsibility," he said.
"I have been playing for Arsenal for almost seven years and I think step by step I am feeling more important inside the group, and I am trying to help the younger players because a long time ago I was one of them!
"Now it is my moment to teach them and to give some advice to them. I want to feel important and to feel involved in the group."
Emery has generally deployed Monreal on the left of a back three - with Sead Kolasinac at wing back - but the Spain international is happy with either of our two defensive formations.
"The most important thing is if he [Emery] feels happy when we play!" he said.
"We have different options in the team. We have played a few games with a back four, we played good games with a back three. It all depends on what team we play against because every game is completely different.
"Sometimes we need to play with a back four and be more defensive because the other team they have the possession so we need to defend better. In other games we are going to have the possession so it’s better playing with three defenders and to have more offensive players.
"It depends on the game, it depends on how we play and we need to be happy and believe in what we are doing and give our best."
