Manchester City manager Pep Guardiola said they cannot take anything for granted when they play West Ham on Sunday, live on Sky Sports.
City are looking to extend their unbeaten run of 19 games and increase their lead at the top of the Premier League when they host the struggling Hammers at the Etihad Stadium.
When asked if the match would be easy, Guardiola replied: "Don't say the word please!
"These kind of things happened in Barcelona. I was asked many times about that when we had good results.
"I spoke well about the opponents and people said 'Pep has false humility, he's a liar, he's saying something he doesn't believe'.
"I can't deny we're in better form than West Ham and have had better results, but tomorrow we start again."
West Ham, who appointed David Moyes as manager after a disastrous start to the season under Slaven Bilic, are currently in the bottom three after losing to 4-0 to Everton on Wednesday.
"I can't think it's already done or it'll be easy," Guardiola said "I can't think, 'It's West Ham we can make six or seven changes and the second team is going to play'. I think that's ridiculous.
"We have to respect them and the best respect to them is to be serious and play the strongest team possible."
