According to the BBC

The summer transfer window will be moved and contracts ending on 30 June will be extended for a short period under proposals agreed by football's major stakeholders.

BBC Sport understands talks initiated by world governing body Fifa and including confederations, federations, clubs, players and leagues have reached agreement over a number of issues arising out of the Covid-19 pandemic.

All parties now accept that completing the 2019-20 season by 30 June, as initially hoped, will not happen.

So much for Thicky's assertion that this couldn't happen!
