David Luiz has said Chelsea are keeping their focus despite increasing their advantage at the top of the Premier League.
Chelsea beat Swansea 3-1 on Saturday to move 11 points clear of second-placed Manchester City.
Luiz told Chelsea TV: "[We] need to go game by game. Premier League everybody knows is difficult. So keep the feet on the floor, with humility, working hard. That's the way."
Antonio Conte echoed Luiz's views and said the current table wasn't a true reflection with other teams having a game in hand.
"[Eleven points] is not the reality," Conte said. "The other teams have to play the game. For sure we have to look at ourselves, to play game by game and to continue to show we are deserving to stay at the top of the league.
"Next week we have to prepare [for] a really tough game against West Ham."
West Ham beat Chelsea in the EFL Cup at the London Stadium in October, but since then Conte's side have only lost once in all competitions and have won 14 of their 15 games in all competitions at Stamford Bridge this season.
"To have 10 wins in a row in the league and 12 in all competitions shows it's very difficult to play at Stamford Bridge for the opponents," he said. "It's fantastic to have this record. Now it's important to continue this record."
Cesc Fabregas scored on his 300th Premier League appearance and hailed Chelsea's character and fight.
Fabregas said: "I'm happy. It's a proud moment for me, a fantastic three points for us.
"We're getting closer to the end of the season and we want to be at the top for as long as we can.
"We showed great character, great fight and we had the three points. Now the most important thing for me is that Chelsea win the Premier League and hopefully we can make this happen."
