Defender Gary Cahill remains convinced Chelsea can pile on the problems for London rivals Tottenham this weekend.
Fifth-placed Chelsea trail Spurs by five points with nine games remaining following Wednesday's loss to Manchester City but Harry Redknapp's once high-flying men are winless in four matches ahead of their trip to Stamford Bridge on Saturday.
Cahill said: "Arsenal are having decent form and Spurs have been hit the last few games. It is hard to keep that momentum going throughout the season. Spurs have been absolutely fantastic but it is tough to keep it going every single game week in, week out. You'll always have a blip in the season and maybe theirs has come now."
