Below is the latest I have @Martyn - undecided but likely to follow Premier League as reported below
For the past two seasons, the Premier League transfer window closed on the Thursday before the first game of the season.
But clubs were unhappy with the rest of Europe being able to trade while their window was shut, so clubs voted to reverted to the old transfer system. However, the planned date of Sept. 1 will now not be used due to the coronavirus pandemic.
Premier League chief executive Richard Masters has confirmed the transfer window will not open until the season ends on July 26. At present there is no official date announced for the window to close,
The EFL has not yet announced its plans, but it is expected to fall into line with the top division having also closed early in recent seasons.
