Let me throw a little bit of common sense into the equation here.
The fact that Berbatov is "languid" isnt what many people are against.
Cantona was most probably the most languid player in Uniteds team for many years, and its well documented that his team mates were sometimes furious about his apparant lack of effort. However, his weaknesses were more than matched by the moments of shear brilliance that he would pull out of a hat from absolutely no where.
I could accept Berbatovs style if, like Cantona, we saw those moments of brilliance that offset his frailties. Sadly we just dont see those sparks of genius.
No one is asking him to be like Rooney, running up and down the pitch, getting stuck in. Thats not his style, and never will be. Hes just not that sort of players. But United paid the money because we believed there was those moments of magic in him that would work in harmony with Rooney, in much the same way Cantona would work in harmony with Mark Hughes. One running all over, the other pulling off moments of genius, and between them creating a strike force that would scare the wits out of opponents.
Fergie for many years has liked to have strikers of different styles. Yorke was very different to Cole, one being more languid, the other being more physical. Cantona and hughes was the same. Even Ruud and Forlan, Ruud and Smith, Ruud and Rooney could all be described in this way.
So those that expected Berbatov to be a highly mobile player were wrong, thats not what he was brought in for. He was brought in, like Cantona, to offer those moments of magic that can suddenly change games and have opponents wondering "what is he going to do next"
For the ball part of his time at United, he hasnt provided those moments. If anything he is so predictable that everyone knows exactly what he's going to do next and thats why hes so ineffective..
