Eden Hazard has said some of Chelsea's Premier League rivals are beaten before kick-off at Stamford Bridge this season.
Antonio Conte's rejuvenated squad head into this weekend's fixtures looking to extend an eight-point gap at the top of the table when they entertain relegation-battlers Swansea.
Chelsea swept Arsenal aside 3-1 in their last home match, which was an 11th successive victory in all competitions in front of the Blues supporters since losing to Liverpool on September 16.
The Belgium international believes such dominance can provide a platform for a successful assault on the title, and he said Chelsea's 2-1 victory over Tottenham in November demonstrated the confidence of the team when they play at Stamford Bridge.
"Yes, it's significant. It's difficult for the opponent to come here and win games," Hazard told the London Evening Standard.
"Do I get that feeling that some teams are beaten before kick-off? Yes. We are playing better than last season.
"It's a little like two years ago when we won the league. I remember the second part of the season back then - sometimes the team didn't play well, but we always scored at least one goal and Thibaut Courtois would make at least one good save, like against Arsenal.
"We are in full confidence here on this pitch. You know the fans bring everything, they support us. I remember against Tottenham earlier in the season when they scored, but the supporters kept going, they kept singing.
"It's great and we feel very good on this pitch. We know everything can happen in football, but we have self-belief and that is very important in football."
