West Ham manager Slaven Bilic claims it would not be a shock if the Hammers beat Manchester City tomorrow.
Away wins at Liverpool and Arsenal have helped West Ham climb to fifth in the Premier League table but City will offer an even stiffer test at the Etihad Stadium.
Manuel Pellegrini's side lost to Juventus in the Champions League on Tuesday but have made a perfect start in the Premier League, winning five out of five without conceding a goal. The Hammers have tasted defeat in their last seven consecutive visits to City, but Bilic believes his side are primed for another upset.
"It would be a surprise of course because before Juventus, Man City scored 11 goals and didn't concede, they are cruising," Bilic said.
"They already have a gap (at the top of the table) which is hard to catch after five games. So on the one hand, it would be a surprise, but to be fair it would not be a shock considering we have done it two out of two already.
"It's good for us, we know what we have to do to have a chance. They are the favourites but I am expecting us to have a good game and if we have a good game we have a chance."
Bilic added: "The quality (at City) is there, it's extreme. Last year it was there also but they now have a few more players. It's scary quality."
