Mari is on a loan contract that expires in the summer.
But Arsenal do have a buy option they could exercise to bring the Flamingo man to North London permanently. He has played only two games so far, but looked impressive in both.
Mari told talkSPORT: "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."
