Antonio Conte feels Chelsea are continually to slowly adapt to their so far successful 3-4-3 formation.
The Blues have won 11 matches in a row since reverting to Conte’s favoured game plan but even if they have experienced immediate joy, Conte suggests it remains a work in progress.
“In the history of Chelsea, this never happened, no?” he said.
“To change it totally, this situation, is not easy – you must go slowly, slowly.
“In my mind, and also before the games against Liverpool, there was the will to change, but I waited until the right moment.
“You always hope not to make great changes to the team. I have players that had only played with four [at the back].”
“After these two bad games, we changed a lot,” he added.
“Usually when I don’t win it’s very difficult to sleep, but now I’m sleeping!
“After 11 wins, we have a positive pressure that we want to continue.”
