Manchester United midfielder Fred was one of nine Premier League players called up by Brazil for the ongoing international window
The six Premier League clubs who refused to release players for Brazil’s World Cup qualifiers “need to be told” if they are suspended.
European Clubs’ Association chief executive Charlie Marshall said clubs need to know “if they can play their Brazilians or not”.
Fifa can ban players not released in an international window for a period of five days after the window ends.
The players called up were Liverpool trio Alisson, Fabinho, and Roberto Firmino, Manchester City’s Ederson and Gabriel Jesus, Chelsea defender Thiago Silva, Manchester United’s Fred, Leeds forward Raphinha, and Everton striker Richarlison.
Wolves, Newcastle, Watford and Blackburn will all lose players this weekend after complaints from the Chilean, Mexican and Paraguayan associations.
