Arsenal couldn't build on three wins in their last four games, as they went down to a 2-0 defeat at Southampton.
The Saints demonstrated their top four credentials with a convincing victory over the Gunners, thanks to goals from Sadio Mane and Dusan Tadic.
Both goals were examples of shocking defending from Arsenal, and the main culprit in both goals was goalkeeper Wojciech Szczesny.
The first goal arrived in the first half as Mane's run down the right bizarrely led to Szczesny coming off his line, and Mane simply clipped the ball over the Pole and into the net from a tight angle, with Szczesny in no man's land.
And following a catastrophic mix-up between defender Mathieu Debuchy and goalkeeper Szczesny allowed Tadic to poke the ball home from close range.
It was a disastrous game for Szczesny, and fans weren't shy in criticising the 24-year-old shot-stopper, taking to Twitter to blame him for the defeat.
Fans not only called for him to be dropped in favour of David Ospina, but also said that manager Arsene Wenger should have signed Tottenham goalkeeper Hugo Lloris before he made the move to White Hart Lane in 2012.
Here are some of the reactions on Twitter from Arsenal fans after Szczesny's performance.
Look at Lloris & look at Szczesny! You know...you know Lloris should've been signed by us when we had the chance!— Alexis's left Thigh. (@SreeSince91) January 1, 2015
Imagine if we had Lloris instead of Szczesny. We don't lose today. Such a gulf in class.— Sidd (@FUTSidd) January 1, 2015
Ospina needs to cash in on his chance against Hull. He can easily outperform Szczesny who reminds me of Almunia.— Hassan Abdullah (@HassanAbdulla77) January 1, 2015
Ospina Starts for the rest of the season IMO it's a must cant stand szczesny anymore— AHRambo (@llbrahimovic) January 1, 2015
Having Ospina in goal will feel safer. Szczesny doesn't seem to be improving.— GoonRambler (@GoonRambler) January 1, 2015
Seriously, every game that happens. Szczesny has a moment of madness. Finally cost us. Ospina time surely.— Dimi (@DimiMAFC) January 1, 2015
Szczesny is just terrible.— JG (@Artekkers) January 1, 2015
Szczesny is an absolute clown sometimes. No idea what he's doing half of the time.— Jarred (@jarred1886) January 1, 2015
Szczesny is such a liability - has no sense of composure and has cost us points here. He needs to be dropped.— The Notorious OBIG (@SmallsObi) January 1, 2015
Szczesny had an awful match today, but I do rate him very highly, he just needs to calm down a bit and take the right decisions.— Attila Takos (@athlon29) January 1, 2015
