I don't blame the players for working with an agent who has shown himself able to extract maximum financial benefits from a comparatively unforthcoming employer. However, it's frustrating that his involvement gets reported as commencing so late in the piece.
For instance, during Nasri's contract negotiation he was not originally involved, but when serious talks began he was reported as having been brought on in an "advisory" capacity.
It's also somewhat despicable for David Dein's son to be negotiating somewhat against the interests of the club, but that's a matter for his own conscience I suppose.
