Arsenal fans have questioned Mikel Arteta's decision to deploy Bukayo Saka as a right wing-back against Chelsea.
It comes as the Gunners take on their London rivals at Stamford Bridge - a venue they have not won at in the Premier League since 2011.
But in recent times, Arteta has proved successful against Chelsea - beating them under Frank Lampard in the FA Cup final last year.
However, with Thomas Tuchel in charge, the west London outfit look a completely different animal.
They find themselves in the final of the Champions League and the FA Cup, as well as looking set to land a spot in the top four of the Premier League.
Arteta has been tasked with stopping Tuchel's side and has made some interesting decisions in his line-up.
One of them being the fact that Saka has been placed as a right wing-back, with Arsenal fans confused by the Gunners coach.
What has particularly irked supporters was the fact that Arteta has three actual right-backs on the bench in the shape of Calum Chambers, Cedric Soares and Hector Bellerin.
One fan said: "Play Cedric/Chambers at RB, Saka at LB, Martinelli/Willian at LW and Laca at CF and Pepe at RW can we not try and build on our previous results without chopping and changing."
Another posted: "3 RBs on the bench and Saka RWB???"
While this fan said: "What did Cedric do to Arteta? Left footed Saka at RWB, while Cedric had decent performances."
And a fourth tweeted: "Saka at the RWB is dangerous, if he concedes possession then we are open to be countered, he wouldn't be able to track back, leaving holding exposed. It's a good formation with wrong player, Saka in particular."
In the Sky Sports studio, even Jamie Redknapp was bamboozled, saying: “It is strange when you’ve got Bellerin, Cedric, Chambers on the bench. They might be more suited to playing that role.”
