Manchester United boss Sir Alex Ferguson feels player power is out of control.

As Carlos Tevez returned to Manchester City, Ferguson told FIFA.com that the balance of power between players and clubs has shifted too far in one direction.

Ferguson said: "To begin with, when I first started out in management 37 years ago there were no agents. 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 tipped completely in the other direction and I'm not sure it's good for the game.

"Of course the way the media works has changed too, there's a lot of pressure on journalists to publish huge news stories - not just about sport but about everything - and that's had an impact on us, no doubt about it."
