Fernandinho and De Bruyne who i think are both good signings for them, Roberts the young lad from Fulham is a very good buy for the future as well, and for what they paid Delph i'd say was a decent purchase as well
Think also Jovetic would have been a good buy if he wasn't made from weetabix - 9 injuries in less than 3 years, 7 in his first two seasons and all of them for between 3 weeks and 2 months.
Ottamendi, Bony, Navas, Fernando and Mangala are strange ones - as can hardly remember reading or hearing anyone criticising any of those transfers until a few months after they bought them, as all three where exceptionally highly rated players at the time, Ottamendi for example was voted the spanish defender of the year in the league last season from memory, same with Negredo really - highly touted and a surprise he failed. But can tell yuo right now if we had signed any of those at the time we would have been bouncing around thinking we had signed some great players - in fact think we where linked with Ferndando weren't we and most felt gutted we didn't get him - msame with Negredo who we apparently bid on
and well Sterling was IMO nothing to do with Pelligrini - just seemed like a club decision to buy a touted english player to me that one did.
Think people just see the money spent by city and get alarmed but in reality a 20m player for them is like a 2-3m player for us, not a disatser if it doesn't work out and they buy that many that some stick.
Similarly i wont give him massive credit for Ronaldo, Kaka, Benzema and Xabi alonso all being signed by him for Madrid either as well - malthough Alonso was supposedly one he isnisted upon
My thinking is judge a manager on how the operate at a level without interferance for a better judgement and in that he ahs done well
