Coming from a goal down to beat Arsenal would usually be enough satisfaction for Swansea City players, but their 2-1 win on Sunday night was given an extra bit of gloss with a bit of Twitter humiliation for one of the Gunners most prominent stars.
Alexis Sanchez is the man making Arsene Wenger's men tick at the moment and he was the one to open the scoring at the Liberty Stadium, which at the time made it look as though his pre-match prediction was not so bad and that there would be a happy ending for his team.
The Chile international went on his Twitter account the evening before the match in Wales to post a smiling photo of him with a select few of his teammates, accompanied with a bold shout: "Going to sleep! Tomorrow those 3 points are coming to London!".
Things got bad for the £32million man just over ten minutes after his goal, when Gylfi Sigurdsson stepped up to a free-kick from about 25 yards out and curled an absolute beauty into the top corner past Wojciech Szczesny.
The humiliation was complete when Calum Chambers' torrid evening reached it's nadir and winger Jefferson Montero skinned him for the last time to stand up the cross for Bafetimbi Gomis to head the winner.
Wayne Routledge was injured for the match, but he got involved in the celebrations afterwards
It was a nightmare for Wenger and the travelling Arsenal fans and the evening got worse as they had to watch their side fail to muster any serious opportunities to get back into the game as the heaven's opened.
Swansea winger Wayne Routledge was injured for the match, but he got involved in the celebrations afterwards with a cheeky retweet of Sanchez's post and a little addition of his own.
The diminutive winger wasn't the only one to take a dig at the Arsenal star, teammate Angel Rangel also got in on the act with a retort, much to the delight of the online contingent of Swansea supporters.
Sanchez was asking for it really and somebody probably should have said something when he decided to put it out on Twitter. Oh well, you live and learn.
Despite this embarrassing incident, Sanchez is still having a terrific season and the Gunners are likely to turn around their poor form if he can keep it up until the raft of defensive injuries is relieved.
