FIFA president Gianni Infantino says English Premier League and Spanish LeLiga clubs need to release players for upcoming World Cup qualifiers next month to "preserve and protect sporting integrity".
The top-flight leagues in England and Spain back clubs refusing to make players available for qualifiers in countries where the players would have to quarantine on their return, particularly South America.
The Premier League says nearly 60 players were to travel to 26 countries on Britain's 'red list', while LaLiga says 25 players from 13 different clubs are affected, with more to follow, when Ecuador and Venezuela announce their squads.
"I am calling on a show of solidarity from every member association, every league and every club to do what is both right and fair for the global game," Infantino says.
"Many of the best players in the world compete in leagues in England and Spain, and we believe these countries also share the responsibility to preserve and protect the sporting integrity of competitions around the world."
England's strict quarantine rules would require players to quarantine for 10 days upon return to the country, with the Premier League saying no exemption had been granted by the government for soccer players.
Infantino has written to Prime Minister Boris Johnson for support.
"I have suggested that an approach similar to that adopted by the UK government for the final stages of the Euro 2020 be implemented for the upcoming international matches."
