Pep Guardiola has come out in opposition to a proposed European Super League.
City are one of 12 clubs who have signed up to the new tournament, alongside Manchester United, Liverpool, Chelsea, Tottenham Hotspur, Arsenal, Barcelona, Real Madrid, Atletico Madrid, AC Milan, Inter Milan and Juventus.
The founding clubs will keep their places regardless of their success on the pitch.
"It is not a sport where the relation between effort and success does not exist," said Guardiola, who revealed he was made aware of the plan "a few hours" before the statement was published Sunday night.
"It is not a sport where success is already guaranteed or it doesn't matter if you lose. I said many times, I want the best competition. It is not fair when one team fight, fight, fight at the top and cannot be qualified because it is just for a few teams."
