Spurs keep leaking goals because Postecoglu will not move away from his high risk, naive style of football and as a direct result, results have been poor and they are massively underachieving. And as results continue to be poor, he responds publically by being more and more of a knobhead to anyone who dares question him.
I dont think City can be criticised too much for letting Rogers go, had he stayed then he wouldnt be where he is now as it has taken him a few years working his way up when he wouldnt have been close to the City side. Porro likewise and he is defensively not the best. Palmer is obviously the one who got away but he seemingly pushed for a move and Alvarez went for a huge fee.
