Chelsea have impressed in the Premier League since Antonio Conte changed the formation to play with three at the back.
Chelsea defender Gary Cahill is pleased with how Chelsea have played in the last three league games but insist that the best of Chelsea is still to come.
“We can’t get carried away after what happened against Manchester United. We are still getting accustomed to this new formation,” Cahill told Standard Sport.
“At the moment it is proving difficult to play against. We have managed to play out from the back well and if we press high, we can cause trouble with the wing backs.
“We are learning as we’re going along but we are adapting the more we use the system.
“It meant a lot to beat Manchester United after losing to Arsenal and Liverpool last month.
“There was a bit of doom and gloom a few weeks ago, but you look at the position we are in now, it’s changed again.
“It’s important that we perform well in big games. Obviously you want to win but the performance against Manchester United was terrific.
“We are pleased with the last three league games, but we are working on improving the way we play all of the time.”
