Fabianski moved to the Liberty Stadium in search of regular first-team football during the close-season, having made 32 Premier League appearances in seven years at Arsenal.
While he is set to come up against a number of friends as Arsene Wenger's side visit on Sunday, the Pole is fully focused on helping his new club to victory.
He told Swansea's official matchday magazine: "It's going to be interesting. Almost all of the Arsenal players that are likely to play are players that I played with.
"It will be a game against some very good friends, but that’s part of football, and I will try to treat it as if it were any other game. Hopefully I will be the one smiling at full-time."
Fabianski has started every Premier League game for Swansea this term and does not regret leaving Arsenal when his previous contract expired.
"They are a big part of my life, and I still have a lot of friends there," he added.
"Being in one place for seven years is a long time and it’s natural to grow close to the club and the players.
"But I made the decision to leave, and I am very happy with that decision and with how things are going at the moment.
"I feel really good here. Everyone has been amazing with me, and I am looking forward to the future."
