I certainly don't think he's a saint, but as I said, it's only in England that we have a problem with third party arrangements. They're quite common elsewhere, especially in the Spanish/Portugese speaking countries.
As for the financial 'irregularities', you'd probably find most very wealthy people have been implicated in somethign or other at some stage.
As for agents, the only thing I would point out is that there are largely two types of agent, one with players on their books and the other without. The latter group are the real problem as they don't appear to actually do anything constructive. The ideal world would have no agents but there are a faoir few who do actually care about the welfare of their clients. They may still be in a minority, mind.
