Manchester United boss Jose Mourinho has backed proposals to expand the World Cup to 48 teams as he believes players would be better protected.
FIFA president Gianni Infantino is hoping his plan to have 16 groups of three teams from the 2026 tournament onwards will be received favourably when the FIFA Council get together next week.
The influential European Club Association - of which United are a member - has already expressed their disapproval, but Mourinho is behind the potential reform.
He told FIFA.com: "I'm totally in favour. As a club manager, if the expansion meant more games, less holidays and less pre-season for players, I would say no.
