Jakub Kiwior was back in the left-back spot on Saturday, earning praise for his defensive display and a goal.
Meanwhile, Arsenal supporters are happy with the defender who has emerged as one of the most reliable members of the squad.
NikoBruder (all reactions via /r/Gunners): "The way Kiwi has stepped up the last couple of games has been incredible. Offer much more stability defensively than Zinchenko, and seems more comfortable in his duties."
topbananaman: "Kiwi has been phenomenal since he's come into the team and stopped inverting. Genuinely do we take him out of the team as soon as the other LBs are back? This is the most secure we've been at the back all season."
Jonny_x3: "Yeah I've got give Kiwior some flowers. We're down to our fourth choice LB due to injuries, title race is starting to hot up, and it's a baptism of fire getting massive games like Liverpool, Newcastle, Porto. Very admirable the way he's stepped up to the plate."
minusa: "Don't sleep on the quality of his balls in behind. He's been making amazing progressive passes... and not of the safe category Arteta would prefer too. Won't be long until Arteta clues on and adds it to the counter-attacking arsenal alongside the Raya quick throw."
Idontlikethisstuff: "I'm so delighted for Kiwior man. Really held his own in that left back spot and got himself a goal as well. It's worth remembering that he's our 4th choice LB as well so to do this well is really impressive."
