In order to be the best at anything you have to have the ability to learn. This will mark two matches in a row where City dominated early, lost their grip and ended up needlessly conceding while having a full bench of fresh legs just spectating.
The only rational reason he's letting this happen again is that he thinks bringing a tie score back to the Etihad is enough to get through. But even that is pretty stupid when you consider they were bossing this match and he just let RBL back into it. I mean, at least make a change to get some more added time to give them a fucking chance.
