Pep isn't happy because he understood how is retrograde this country about football. He likes a type of football with the ball between the feet and not in the air, he likes and respects a class of journalists with a passion to know and to understand and not to provoke. England are refusing to understand Pep (and are blaming him) like in the past with Arsène Wenger. England is, was and will be connected forever with a precise idea of football: tackle, long ball and a proper number 9 on attack, like in Italy. Italian and English football ideas are similar. This is the secret why Ranieri last season and now Conte are loved.
Talking about the squad, in my humble opinion, many players has deluded him. He hasn't neither a good defender, a stone to build the defensive movements around him. Kolarov is shit as HB, Otamendi plays one good game and three bad, Kompany is injured and Stones isn't yet ready to play for a top class club.
Kevin de Bruyne and Aguero pushed forward the team only thanks to their immense qualities. Probably we will see a different City when they will build a new defense in front of Bravo (another wrong choice because isn't better than Caballero and Joe Hart), with a new midfield with Ilkay as playmaker and a mobile attack.
Manchester City are miles away from the idea who Pep has about football. The strange thing is one: despite all the problems and mistakes, they are 3th.
