The Spaniard arrived at the Gunners in January from Flamengo on loan and could be a permanent fixture if the club exercised a buy option.
He would like to stay, and he has praised Brazilian Luiz in helping him transition to England and the Premier League.
Speaking to talkSPORT, Mari said: "I've been at five clubs over the last four years. This is a footballer's life.
"If you want to play football and you want to improve [to get to a big club] then every year you need to move.
"Maybe when you find a club that is good for you, then you can stay and improve with that club.
"I have found myself here at Arsenal. It is a really good option for me.
"I want to stay here and improve as a player and a person. I want to be here for many more years."
