The defender is on-loan from Brazilian champions Flamengo.
“Of course I have a lot of things I can improve but I think my football can be really good with Arsenal, and also with the coach," Mari told Sky Sports.
“So, I hope that me and the club go at the end with good things to do a permanent transfer. But we will see because at the moment with the virus it is a little bit difficult."
Where the Spaniard has clearly settled with Arsenal, he also reveals he has become accustomed to living in England.
“I love England and so does my wife," he said. "The centre of London is unbelievable. We are really happy here."
