It's a bit of a fine line though I reckon. I think there is room to say that while Rooney has become a top player, he hasn't developed into the type of player initially predicted.
And while 'The White Pele' is of course an extremely high standard, the point was - that was genuinely what people thought Rooney was capable of becoming. I mean, Messi was often compared to Diego in his younger years, and he has since gone on to justify that (and then some!). Many thought Rooney could go on to be one of the greats of the game, but then I don't think the answer is always to say in hindsight that 'those predictions were too harsh/impossible'. Some players are actually that talented that they can go on to justify, as Messi has proven. Therefore, perhaps Rooney was put into that bracket himself, and as good as he has become, he has still fallen short of it.
It's easy to say it was unfair to compare Rooney to the greats but very fair to compare Messi to the greats in hindsight. At the time, United fans would have been arguing with everyone left, right and centre that Rooney was not inferior to Messi and Ronaldo.
That's exactly it though. This whole Messi/Ronaldo comparison stuff is crazy. We're talking about two players who reallly will go down in history as up there with Pele and Maradonna.
Implying that Rooney is somehow an unfulfilled talent on the basis that he might not be considered one of the best 3 or 4 players ever to have kicked a football is really just a reflection of how silly it is to call any young footballer "the next Pele/Maradonna/Messi/Ronaldo". There's a whole lot of absolutely fantastic footballers in a tier or two below that and it's borderline disrespectful to consider them as also rans because they didn't reach the very pinnacle of footballing greatness.
