Arsenal fans had plenty to celebrate after their 2-1 win over Liverpool on Wednesday night.
The Gunners came into the clash on the back of a disappointing defeat in the North London Derby and their opponents - the Premier League champions, no less - had lost just two games all season.
Things didn't start particularly well for the home side either as Liverpool seemed to get into their stride early on, taking the lead when Sadio Mane converted from Andrew Robertson's cross.
Arsenal overcome Liverpool
From that point on, however, Liverpool seemed to fall apart with Virgil van Dijk giving Arsenal an invaluable chance to get back into the game after a terrible back-pass.
Alexandre Lacazette was on hand to capitalise by rounding the goalkeeper and it was the Frenchman again who intercepted when Alisson Becker made a similar passing error.
On that occasion, Lacazette turned provider with Reiss Nelson applying the finishing touch to put Arsenal 2-1 up at half-time and leaving Liverpool with all the work to do.
Should Alexander-Arnold have been sent off?
The Reds did apply the pressure after the break as you would expect and it took a glorious save from Emiliano Martinez to keep out Trent Alexander-Arnold's deflected shot in stoppage time.
And there's multiple reasons why Gooners would have been particularly upset if Alexander-Arnold had drawn the scores level late on and it's not simply because they wouldn't have won.
Rather, there was good reason to think that Alexander-Arnold shouldn't even have been on the pitch by that point after a controversial tackle on Bukayo Saka.
The young full-back went studs up into Saka's leg at speed, sending him down to the ground in visible pain.
Aubameyang makes his feelings known
Referee Paul Tierney duly awarded Alexander-Arnold a yellow card, though VAR did not review the original decision, which caused plenty of anger across social media.
And it seems that this dissatisfaction has spread from Arsenal fans to Arsenal players as top goalscorer Pierre-Emerick Aubameyang reacted angrily to a photo of the challenge on Twitter.
The Golden Boot contender simply wrote: "WTF didnt Even get the VAR on this one."
Plenty of Arsenal fans agree
There are plenty of Gooners who share your sentiment, Pierre-Emerick, with many drawing similarities to the challenge that earned Eddie Nketiah a red card against Leicester City.
You can forgive Arsenal supporters for feeling miffed that their young striker was awarded a three-match suspension for his action whereas Alexander-Arnold will be able to play in a few days.
What do you think: did Alexander-Arnold get off lightly? Is Aubameyang bang on the money?
