Since Antonio Conte’s switch to a 3-4-3 formation, the Blues have enjoyed 3 perfect victories, winning against Hull City, Leicester City and Manchester United.
Cesar Azpilicueta who plays on the right side of a 3-man defence in the new formation has applauded the new system.
“I find it good,” he told Sky Sports.
“The most important thing for me is the team and since we changed the system we haven’t conceded goals in the Premier League.
“I try to play my part in the team. The most important part of the system is the spirit of the team and the way we work.” He said.
