On June 11, 2020, Fifa passed a series of temporary amendments to help deal with the impact of the coronavirus shutdown on the football calendar.
One of the key changes allows the first registration period, also known as the summer transfer window, to overlap with the delayed end to this season by up to four weeks.
Normally, the transfer window does not open until the season has been completed, but many leagues are only just restarting after being halted in March and will not finish until late July.
However, while transfers will be permitted before this season ends, clubs will not be able to field new signings until the next season begins.
The same rule will apply to players moving under freedom of contract.
The transfer window can stay open for up to 12 weeks.
La Liga president Javier Tebas has indicated that the window in Spain will only open once the season has been completed and will run from late July to early October.
Similarly, Premier League chief executive Richard Masters has said that the window in England will also only open once the season has finished.
However, in France, where the season was declared over in late April, the domestic transfer window opened on Monday.
