Everyone at Chelsea agrees on the who. The players, the coaches and the platoon of staff members behind the scenes all say that, in six months as manager, Antonio Conte has transformed the club. He has given a team that seemed to have lost its shine the veneer of a champion.

Nobody has any doubt about that. After all, the evidence is overwhelming: Chelsea, only months removed from a season in which José Mourinho’s second coming came crashing to a screeching halt, is purring again. Conte’s team sits 5 points clear at the top of the Premier League. Beat Tottenham Hotspur on Wednesday, and not only will that lead stretch to 8, but a record will be claimed, too: It would be Chelsea’s 14th consecutive win, the best single-season run in the history of the Premier League.

Nobody has any doubt that Conte is responsible. What they cannot quite agree on is how.

There are as many different explanations as there are players on his squad and staff members at his disposal. Defender Gary Cahill stresses the tactical shift, the switch from a four-man back line to a 3-4-3 formation. Striker Diego Costa, revitalized and repurposed up front, pinpoints Conte’s more human touch. “Every time, he is making more jokes with the players,” Costa said.

Pedro, a winger, believes the answer is simpler still. “He put trust and belief in all of the players, and we started winning matches,” he said. “Quite easily, he just turned things around.”
