Personally, I don't think we should be looking at more than three foreign world class players.
I want to see Pep mould a team that has enough class in it (Aguero, Kompany, Toure, Fernandinho, Pogba, Gundogan, De Bruyne, etc) with young players that are hungry and have an affiliation with the club. We have plenty in the U18s that given the right coaching, chances and encouragement, would be far more useful and have a long term passion for city.
We're not going to get anywhere by bringing in 8 or 9 players that will just end up in the same boat as players like Kolarov, Nasri, Mangala, Otamendi, Navas, Bony, Fernando, and before them Jovetic, Negredo, etc.
I want a team that has character, fight and aggression which is mixed with technical ability and guile. We are buying too many that look good in shit leagues or stand out in a poor squad, they aren't going to help us to develop a togetherness and will to win that we are so lacking in right now.
