Window to close before new season

This means clubs will not be allowed to register any new players after 5pm on Thursday, August 9, 2018, but they will still be able to sell players to clubs in leagues where the window is still open, as is currently the case.
In a short statement, the league said: “Premier League clubs have today agreed to a rule amendment that will see the summer transfer window in any year end at 17:00 on the Thursday before the start of the season.
