The early finish will not mean the Premier League’s transfer window is shorter as it will start earlier and be 12 weeks long, in line with Fifa rules.
Next summer is slightly different from normal, with the 2018-19 season following the Fifa World Cup in Russia, which finishes on 15 July.
Premier League clubs can still do business during the tournament, but will now have only 25 days after its conclusion in which to complete signings.
In August, Tottenham striker Harry Kane said closing the window early would allow players to concentrate.
His views were echoed on Friday by Arsenal boss Arsene Wenger, who stated players need “clarity”.
“It’s important that we close all that stuff before the championship starts,” said Wenger. “Players have no clarity. Are they in? Are they out? Will they be tapped up on the afternoon of a game? It’s not the way to work.”
