This'll sound biased from me but I was thinking about the cream de la creme players of his generation and is he really in there, At the top?
He's probably one of the most overestimated players around and when it's all said and done hid reputation can only go down, for me the very best of players not only leave a mark on their teams bur are undoubtedly indispensable when it comes to winning titles and for all his attributes he Simple isn't that sort of the player, of all his years at City I can't remember a single decisive big game performance from him which was pivotal in them winning the league and in Europe which let's be honest is all that matters to city at this point he was insignificant both times they managed to get to the final, hell as fate would have it he missed those two games due to injury anyway.
Not to mention he was unavailable for significant periods of time for some of their campaigns and city went about their business just about the same, a damning fact, just compare that to when rodri is unavailable.
His international career is somewhat more disappointing as hazard stole the spotlight when he still hadn't gone awol to be their clear main man when Belgium had it's best performances result wise and when he did get the chance to be their talisman he failed to leave his mark, with disappointing results which followed.
All in all he'll be rightfully called the best of his position at England for the duration in which he played at city but I don't think he'll have any business cracking a top 20 premium league player of all time for example never mind being on the all time great ones.
