Petr Cech’s arrival in north London forced Szczesny to look elsewhere, having previously made over 150 appearances for the Gunners.
He still has a year left to run on his current contract and acknowledges that he could end up back in the Premier League for 2017-18, having impressed with his showings in Serie A.
Szczesny told BT Sport: “Staying at Roma? I’m happy here. I feel I’ve grown as a goalkeeper but for me the time to make a decision will come in the summer.
“For now I’m an Arsenal player, as soon as my loan finishes, I have to come back [to London]. I’ve always said I’d love to be back there.
“Like I said, what will happen definitely won’t be decided now but in a month or two months’ time.”
While leaving the door open for a return to the fold at Arsenal, Szczesny believes both his confidence and form have improved with regular football at Roma.
“I came here after a terrible season,” he added.
“I was in a bad moment. It was a good chance for me to re-launch my career.
“Coming here and having a fresh start, new challenges, new league helped me to mature a little bit as a player.
“My best season? I’d say so, yeah. In terms of consistency, it definitely is. In terms of quality, I feel at my best.
“Am I the best goalkeeper in Serie A at the moment? It’s a big statement to make. There are goalkeepers on an unbelievable level here.
“I wouldn’t dare compare myself to [Gianluigi] Buffon, not as a man and not as a keeper. I’d never make that statement, no.”
Szczesny has made 78 appearances across two seasons with Roma, helping them to back-to-back top three finishes and qualification for the Champions League.
