There are reports the Premier League could abandon its new-look transfer window after just one season.
The Mirror report that at least two clubs who voted to shut the window before the season began now believe it was a mistake and want to go back to an August 31 deadline.
The early end may have also put Premier League clubs at a disadvantage with clubs in Germany, Spain and France able to sign players until the end of the month.
Premier League chiefs are likely to discuss the transfer window at their meeting next month and if a club proposes a change, 14 clubs would need to vote in favour.
The change was announced last year after several managers spoke out against the window shutting after the season began, causing chaos for some managers’ plans.
Last season, Alex Oxlade-Chamberlain played for Arsenal against Liverpool – and then completed a £40m move to Anfield just days later.

The change seems to an August 9 closing date is seen as a success by many, despite the World Cup hampering clubs’ planning in the off-season.
