Manchester City boss Pep Guardiola believes Chelsea, Manchester United and Arsenal are serious title challengers this season.
It comes after Jose Mourinho told Super Sunday only City's B team could rival Manchester City, Tottenham and Liverpool for the Premier League crown.
But Guardiola, whose side face Spurs at the Etihad, live on Sky Sports Premier League on Saturday, believes it is more than a three-horse race.
"I am really impressed with Chelsea and how they have played against Manchester United and Liverpool," Guardiola said. "I was really surprised how well Frank Lampard's team played.
"And we saw the quality United have upfront and the new mood around the club. Arsenal have bought good players too, so they are all contenders."
Pochettino has done 'overwhelming job'
Guardiola was also full of praise for Saturday's opponents Tottenham, particularly the job his opposite number Mauricio Pochettino has done.
"Since I came here to England, Tottenham have been a real contender every season," Guardiola said.
"The first season they finished second… they've always been there. They're the second best team in Europe.
"I can't say anything against Tottenham's quality, capacity and the possibilities of the team.
"They are a strong team, a good team and Pochettino has done an overwhelming job, extraordinary.
"My opinion of him is very high, he is a top, top manager."
