Manchester United boss Sir Alex Ferguson says agents are hurting the game.
He insists the involvement of agents bargaining to get the most lucrative deal possible is becoming detrimental to the game of football.
"When I first started out in management 37 years ago there were no agents," the Scot said.
"Imagine that. There was no freedom of contract either, so players were totally tied to their clubs.
"A change in that sense was inevitable, though I think that now the scales have topped completely in the other direction and I'm not sure it's good for the game."
