Aguero's issue with the general public has always been the fact he's consistently been one of the best, but not quite the outright best in any given season. So people have just become accustomed to his excellence and taken it for granted. You listen to people talk about the best ever, all the names mentioned all had that one standout season where they just dominated the league, not necessarily the most consistent*. That's why people act like Suarez did more than Aguero, because of one admittedly incredible season. Aguero's injury issues have taken that away from him. With his repaired knee and continued progress under Pep, this could be his year. Although that seems unfair, as we know just how incredible he is and he shouldn't need one perfect season to prove it.
Also non-City fans have their agendas too. Easier to argue that Aguero's not that great than admit maybe Bergkamp wasn't that incredible a player, compared to Aguero, despite his ridiculously god-like technical ability.
In ten years time I can assure you Aguero will go down as a true legend in the non-City fans eyes. It's just that romanticism doesn't tend to happen until after a player's gone.
*The irony here, is that people spoke about City of last season as not being the best, as they haven't done it with any consistency and one season doesn't count for anything. Maybe people just find it hard to admit how good City and their players truly are.
