Philippe Coutinho's Liverpool future is in doubt and he has missed their opener

At least 14 of the Premier League's 20 clubs must agree for a new rule to be introduced.

One consideration is whether Premier League clubs will be weaker if the summer window closes in the middle of August.

But some clubs are understood to believe it would be better for the league's integrity if none of its teams could add to their squads from the first match of the new season until the January transfer window.

Paul Clement, Swansea City manager, said after Saturday's draw at Southampton: "Our club would support that decision. The majority of clubs are in favour but maybe all have to be for it to go through. It could happen next year."

Transfer windows in January would be unaffected as current proposals only relate to the summer months.
