Brilliant player, the best overall player for me even if the best dribbler title does go to someone else, he is the best but you'd be mad to pay £80m+ for him regardless of how professional he is in training or the shape he's in. That slowing down that happened to Rio, Giggs etc will happen to him sooner or later, and there's been many players than go into decline even before 30.
Thinks its all the nostalgia with him and United causing people to mentally spend the money with their hearts not their heads in their daydreams. We miss out on many of the young Neymars, Messis, Ronaldoinhos or whoever, luckily we did get Cristiano Ronaldo at 18, so lets leave it at that and move on. If of course he was in a situation to come back to Old Trafford for free out of contract or Real let him go cheap out of respect for his service like Fergie did Wes Brown then fair enough, but that' ain't gonna happen is it.
Top player though and him being a bit of an arse is no doubt what has driven him to the top. I mean Nani can pull off most of the tricks he can, probably even more (see Arsenal) but didn't have it up stairs to go top level. Ronaldos the kind of guy who gets booed and then will bang in a penalty top corner against England, no worries and he'll think he's the best doing it.
