Arsenal fan @AtwoliiYa wrote on X: "We are cooked you don't miss such a penalty."
Another supporter @nickraj4real was also shocked, posting: "He never does that. If you're gonna dink, you better score, massive opportunity to kill it for good."
And @DavidBl74071930 added: "Terrible penalty try that nonsense on a night like this is criminal," while @Gunner_Opinions posted: "Thinking that he's world class when he's a glorified Theo Walcott."
Meanwhile, journalist @RafaelH117 added: "It’s not like Saka had a bad history taking penalties, like missing one in a Euros final, right? And a f*cking panenka vs Courtois of all keepers, embarrassing."
