Not nice seeing him joking around at the full time whistle, I doubt he'd behave like that if Argentina were whacked by four.
I've a feeling this will be his last season, he's been absolutely sublime at times but maybe Pep and himself aren't on the same wavelength.
I've nothing concrete to substantiate this, it's just a hunch really and leaving him out tonight was probably the beginning of the end game.
Guardiola was probably pissed off he played twice for Argentina, especially with our run of fixtures in October.
From Aguero's perspective, i don't see him being the well disciplined machine that the manager wants.
