The rule only affects players bought by a Premier League club - and teams in England will still be allowed to sell players to other leagues in which the transfer window is open. It was a miserable end to Arsene Wenger's 22-year career at the club, with no trophy and a second successive season without Champions League football.
And that could trigger a spending spree before the World Cup.
The Premier League season is over, the World Cup is approaching, that can only mean one thing - the opening of the transfer window!
The window closes at the same time as the Premier League, on August 9 at 5pm - five days after the new EFL season begins'.
Press Affiliation Sport understands officers have opted to tug the opening again to subsequent Thursday in an effort to adjust to a Federation Internationale de Football Association rule which requires no less than one window to open for 12 weeks.
The thinking behind it from the clubs is that players will not become unsettled with transfer speculation once the season has kicked off on August 11. "But there are so many reasons why it's nearly impossible to get all your business done early".
EFL clubs will still be able to sign players on loan until August 31. Clubs involved in play-offs can sign players now - but cannot play them until their season is over.
"So everybody knows the players we have and the deals will be done earlier and nobody would be waiting for the last week". If Belgium reach the latter stages, will Marouane Fellaini be prepared to wait until mid-July before moving as a free agent from Manchester United, or would it be wiser to agree to a deal before Russian Federation to ensure that he is not distracted by concerns over his future? The beginning of a summer tour is another cut-off point, but some clubs will fly out to the United States or Far East before the World Cup final is played on July 15, which is another problem to deal with.
When does the Premier League transfer window open? . If they decide to cash in on a player, he can not then be replaced until January, but if the money is too good to turn down, which route do they take?
Fixtures for the upcoming 2018-19 Premier League season will be published on June 14 at 9:00 BST - which is, coincidentally, the same day that the World Cup starts. Some of them will be costly.
