Look, Torres sucks. But we thought it was just a slump he was going through. Before that, he was comfortably one of the best in the world. Not only that, but he was (and still is) a massive draw. He sells shirts with ease. He's on front of magazines. He's in adverts. All of that has to be taken in consideration and that is why he his price was that high.
That's why :mon was allowed to pay Heskey such high wages.
