Jose Mourinho has ruled Manchester United, Chelsea and Arsenal out of the Premier League title race, with Manchester City's 'B' team ranked as a stronger team.
The new top-flight season began on Friday night as last season's runners-up Liverpool thrashed newly promoted Norwich City 4-1 at Anfield.
The following lunchtime, reigning champions City responded by putting five past West Ham at the London Stadium.
Tottenham, who finished behind Chelsea last season, survived a scare to beat Aston Villa 3-1 in north London.
Appearing as a pundit on Sky Sports ahead of United, Chelsea and Arsenal's first games, Mourinho was asked how many teams can challenge of title.
He said: "Four. Man City, Tottenham, Liverpool, and then Man City B team."

Pep Guardiola boasted a strong bench on Saturday, with the likes of Ilkay Gundogan, Sergio Aguero, Bernardo Silva and new signing Joao Cancelo all not in the starting line-up.
Mourinho added: "When I looked at [Man City's] bench yesterday, the players not involved I think even the B team could fight for the title.
“I want to say that the obvious thing, we would love United & Chelsea at that level.
"In football, sometimes unpredictable things can happen, but I think we all agree, a team last season that won everything in England last season and the European champions.”
