Manchester City boss Pep Guardiola insists Chelsea and River Plate have superior teams.
The champions saw off Brentford 2-0 on Wednesday to tighten their already firm grip on the title race.
Their form continues to attract plaudits but manager Guardiola, who felt his team had needed to dig deep and be patient to see off the Bees, claimed only to be interested in results.
He said: "We are not the best team in the world. The best team is Chelsea, who won the Champions League, or River Plate, who won in South America.
"The important thing is we won the game and in three days we go to Norwich and have to win again.
"This type of thing about who is the best, I don't care. Just be happy and try to play better every day."
