In turn, it has played a significant factor in why the club are top of the Premier League table after 24 games, and after Tottenham Hotspur slipped up at Liverpool on Saturday, they have the chance to stretch their lead on Sunday when they take on Burnley.
Chelsea manager Antonio Conte will receive a new contract with pay hike if the Blues manage to win the Premier League title in the Italian's first season in charge - as per the reports from Daily Mail.
Conte will be hoping that focus, both Willian's and the team, secure them another three points when they play Burnley on Sunday.
"Honestly, I think there are six teams very strong and can fight to win the title".
Elsewhere, Conte has revealed he has no intention of selling Brazilian forward Willian amid interest from Manchester United. Now I think also Pedro is playing very well, is in great form.
"There are 14 games to play".
"We've taken the game to a lot of big teams coming to our place this season - City and Liverpool have found it hard, and that's what we want to do again on Sunday".
"He's fantastic on the ball, he's got a lot of good qualities and it's going to be a tough test for us but one we'll relish and enjoy".
Who will come out on top in the battle of the managers Sean Dyche or Antonio Conte?
There are no weak links in the Chelsea side with the team having a series of brilliant match winners such as Eden Hazard and Diego Costa alongside an excellent defence protected by the influential N'Golo Kante. They know how they want to go about things.
Conte and his players can be fully concentrated on the Premier League, since they don't participate in the UEFA Champions League this season and that is big advantage compared to Arsenal and Manchester City. My players know really well the game that we will face.
"Until the end of the season you have to live with this pressure", Conte said. For me Cesc is an important player, and I try to put him always in the best condition to give his best for the team.
Burnley's form at Turf Moor this season has been nothing short of spectacular. The Blues of course are high on confidence and will be hoping for yet another three points but if Conte decides to rest a couple of his key players and underestimate this Burnley side then I feel the home side could get a result.
