The Pole put in a wonderful performance against his old club Arsenal.
Swansea fans were in dreamland last night after a phenomenal defensive performance saw the Welsh side go to Arsenal on Monday night and leave with a 1-0 victory.
Swans striker Bafetimbi Gomis came off the bench to score the only goal, planting a late header over the line, though referee Kevin Friend needed the help of goal-line technology to make sure David Ospina hadn't kept it out.
The Colombian wasn't a match for the player he effectively replaced at Arsenal, with 30 year-old Fabianski rightly receiving plenty of praise on Twitter from exuberant Swans fans.
Garry Monk's side have now beaten both Arsenal and Manchester United, home and away, this season.
Below is a selection of some of the best tweets in praise of their goalkeeper:

Great defensive effort from the entire Swans team but Fabianski's handling was utterly superb. When other keeper would puch, he holds!— Guto Llewelyn (@GutoLlewelyn) May 11, 2015
