Manchester City boss Mark Hughes has made good on promises of a new strict approach to life at their Carrington training complex.

Entrance to the football factory, as Hughes describes it, is by appointment only and carefully screened. Mobile phones and iPods are out. If any player doubted there would be changes after Sven Goran Eriksson's relaxed regime, they now know better.

Hughes said: "There's no longer an open door to everybody. Agents and every Tom, Dick and Harry were allowed into the building, and that's not the case now. Certain structures have to be adhered to, or you end up with anarchy.

"The training ground is very much a working area now. I'm not really one for putting down strict guidelines. But what the players have to understand is that there are certain boundaries which shouldn't be stepped over.

"It's not revolutionary making the training ground our place of work. Maybe that wasn't the case before. Too many people had access to the building, the inner sanctum. It's where we try to hone our skills. It's a football factory.

"Most people aren't allowed to go to see their mates when they're working in a factory, so why should they be allowed to come to our factory? The players can see the benefit. It's helping us create the atmosphere that we need."
