The Swans goalkeeper will line up against the Gunners for the first time since his summer move to the Welsh side from The Emirates.
Arsene Wenger sold Fabianksi after the Poland international had grown increasingly frustrated at being second-choice.
And the Swansea goalkeeper is focused on helping the Welsh side seal three points against the FA Cup holders at Liberty Stadium.
“It’s all about the game, it’s all about three points,” Fabianski is quoted as saying.
“When I get to the tunnel and see some of my former team-mates – my friends really – standing on the opposite side then it will be a funny experience for me.”
Fabianski has kept five clean sheets in 10 Premier League games this season.
