"I want to win trophies. When a player ends his career, he wants to be able to look back and feel that he was an important player and to have some medals," he told El Mundo Deportivo.
"That is what everyone aims for. I want to win and I am happy at Arsenal, but we have four years without any success and, for a player that wants to win things, that is a long time.
"It is clear that it would be special, but I am also clear that Arsenal made me captain for half a season and that has brought added responsibility and ties me to the club even more.
"Now I would really like to lift a trophy as captain of the Gunners."
"If that happened, it would be unusual. I would be delighted," he revealed.
"Pep has always been my idol. I have always played in his position and wear the number four like him. He was my hero when I was young and the one I have tried to be like.
"I tried to imitate what he did as a player and now, as a coach, he is showing how good he is. He is someone that will always be important in my life."
"That is a difficult thing to answer, because I am not the coach of Barca. I think that all good players can play together and have an understanding, but I insist I am an Arsenal player and I cannot talk about this," he added.
