Some pretty disingenuous takes there. Pep's reaction was nothing like what they tried to make out. The 12 shots to 4, makes it look like Arsenal created 12 clear chances. They didn't, most of their shots were from outside the box, all but 2 were blocked or went over. The 2 shots that were on target, including the goal, weren't clear chances either. One was from a tight angle and went straight at Eddie. The other was going to be comfortable save but didn't get past the defenders infront of him, deflecting off Ake's head. That's why City's xg was higher than Arsenal's, despite only one shot on target out of 4. The best chance of the whole game fell to Ake, who didn't get that on target either.
... But I guess pointing all of that out to anyone who isn't a City fan, would be taking it too serious. They rarely are that accurate, it's just a bonus when the takes are factual. They are mainly made for rivals to laugh at your club's expense. To be fair, they've all been waiting a while for the chance to do that. So for my part, I'm not fussed if they are going over the top about it. That shows how far City have come, that they have to reach so much with it, if anything. Flipping the perspective and turning it into a complement, would probably frustrate the shit out of them too. :)
