I am putting this loss (our first of the season no less) firmly at the feet of Pep.
Say what you want about Joao’s mistake—and there is quite a lot to be said—but it should have never been 0-0 by that point in the first place.
The system was wrong, the tactics were wrong, and the sub (1 of 5) were wrong. Our lads generally didn’t play that well, to be sure, but I think a large part of that was down to the formation and tactics: Kev was wasted on the RW, Ilkay was unnecessary, if not actually a hinderance with his instructions, Phil seemingly being told to retain possession at all costs rather than test Milner.
Pep is a genius, and I wouldn’t swap him for any other manager in the world, but he got this one wrong.
