I think after a while to cool off and dissect things yesterday.. there were 5 things that came to mind.
1. Arsenal came to injure our players and steal a win on the counter.
2. They seemed younger, faster, hungrier especially against Walker and maybe Bernardo. The rest of the City players held their weight and justified their selection. We were solid in the other areas.
3. Rodri injury rattled us for a good 15 minutes
4. Once they went ahead 1-2 they gained so much confidence like they could do the 1-6 and signal a powershift they became boneheaded and got the red card.
5. The Red Card affected us more than them.. they setup a low block and the entire City strategy seemed to become Ruben/ Akanji at the pivot and Kyle Walker/ Kovacic long shots.
Pep had a bad game.. he went to his most trusted and stuck with them but they didn't pay dividends (almost exactly like Sterling in the CL final)
And I'm purposely not faulting Gvardiol for giving away corners because he defended great and a defender is permitted to give a corner away rather than a tap in. However that corner needs to be defended and Walker didn't do a good job.
