Chelsea goalkeeper Petr Cech has warned Manchester United and Arsenal that his side are ready to take advantage of any more stumbles from their Premier League title rivals.
Carlo Ancelotti's side, who host struggling West Ham on Saturday, are the Premier League's form team after winning five and drawing one of their last six matches.
That run has catapulted them back into the title race just in time for the season finale.
In contrast, leaders United - who entertain Everton on Saturday - dropped two points in a 0-0 draw at Newcastle on Tuesday.
Arsenal, who travel to Bolton on Sunday, have fared even worse in recent weeks, with five draws from their last six matches leaving them in third place.
Spurs striker Peter Crouch concedes his team must beat West Bromwich Albion at White Hart Lane on Saturday to stay in the hunt, but the England international claims all the pressure is on City.
Bottom of the table Wolves host Fulham, while fourth bottom Wigan face a massive clash against Sunderland, who are five points from the relegation zone and look in freefall after losing eight of their last nine matches. Assistant coach Gary McAllister will take charge of Aston Villa against Stoke.
