Premier League bosses have criticised a Fifa ruling that could see their Brazilian players banned this weekend over Covid-19 protocols.
Under Fifa rules, players not released for the recent South American World Cup qualifiers can be banned for five days.
The Premier League, the relevant national associations and Fifa are continuing to try to resolve the issue.
However, BBC Sport has been told clubs are seriously considering ignoring Fifa and fielding the players in question.
Liverpool boss Jurgen Klopp has said he is unsure if Alisson and Fabinho are available, while Manchester City boss Pep Guardiola is hopeful Ederson and Gabriel Jesus will play.
