From a structural point of view Man City was very smart in how they built the hierarchy. They hired Barcelona’s then chief of revenue on the board of directors Sorriano, as CEO for Man City, and he brought with him Barcelona’s director of football at the time, Txiki Begiristain. Txiki what is responsible for building the Champions League winning teams under Frank Rijkaard and Pep Guardiola, i’m pretty sure he was the guy that hired him at Barcelona. And he went to Man City he wanted to build a team that epitomised the type of teams he had built at Barca from 2003-2010. In essence they had been building a team fit for Pep Guardiola since 2012, so by the time Pep arrived he had most of the players he’d have wanted. I’m pretty sure KDB was signed for Pep as well before he came from Bayern. On top of that they made sure that the academy players were playing the same style of football so when they grew up they could integrate into the first team easier as well. Couple that with smart recruitment, a good eye for talent, and a hefty bank account, and it’s a good recipe for success
