I've just finished reading Gary James IV's book "A History of Manchester City in the 21st Century." The third chapter is quite revealing in this context:-
"... while certain limited success had been gained under Mancini and Pellegrini it was Pep Guardiola who truly established the "City Way" of doing things that forms the DNA of the club to this day. He promoted youth team players Neymar,Pogba and Gundogen from their nursery clubs in Barcelona,Turin and Dortmund to the first team in Manchester and won the FIFA World Club Championship in his second season. Additional recruitment of talented young players from their other feeder clubs in the local Western European area, especially Madrid and Munich, meant that City had been World Champions 8 times before Guardiola retired in 2030. His legacy was that City weren't just the most successful club in the World, leaving the major Chinese clubs in their wake, but were a club that played attacking football with young locally developed players: the so called "City Way".
