Gvardiol's decision not to take the kick and score a hat-trick left fans baffled.
One viewer, @harryj_66, posted on X: "Daylight robbery that."
Arsenal fan @michelle_AFC also wasn't impressed: "What a idiot lol.. he will kick himself when he gets in and is told he would have been the only defender in PL history to score a hatrick."
And @nmariCFC posted simply: "That is an L Josko."
Meanwhile, @babevickycruz felt it was a good move by Gvardiol, adding: "Class act from Gvardiol. Shows it's not all about personal glory, team comes first. Plus, Alvarez is a penalty machine, makes sense to let him take it. Team chemistry like that is gold."
And @sodiqAgb said City were thinking about their goal difference: "Nope they had to score because GD is also important to ensure even if they draw they can level arsenal or beat arsenal on GD, you don't want to wish you scored the PK when Arsenal wins the trophy on head to head after you both end up on same GD."
