Chelsea have had great recent success in the Premier League with a 3-4-3 formation, but it has come via lots of tinkering.
Antonio Conte has revealed that Chelsea's success with a 3-4-3 formation has come about by accident after actually being his plan D.
Chelsea began the Premier League season well as they recorded three successive wins, but a draw with Swansea City and two defeats to Liverpool and Arsenal in September proved they still had a long way to go.
Conte's first four months in charge of the club have seen him tinker with various tactical set-ups, but following the loss to Arsenal the Italian set on 3-4-3.
