Cahill sees Chelsea's strength at Stamford Bridge as key to their title chances.
Cahill told the London Evening Standard: "It's an incredible record. We have confidence whenever we play at home and always manage to get results here. Hopefully, that will continue for the rest of the season but the main thing for us is consistency.
"We do turn up against the big teams, we've put in good performances against them and not dropped too many points.
"If we can stay consistent, which at the moment we are, we have a good feeling and we're going about our business quietly."
