A goal from Marco Arnautovic after six minutes was enough to see off Chelsea in the London derby and Conte has blamed his players' tiredness due to their punishing schedule.
"Maybe today many players were tired," he told Sky Sports after the game at the London Stadium. "Also because we made a lot of mistakes in the final decision, important decision and it means we are a bit tired."
"But when you play every game in two days almost always with the same players, it can happen," the Italian stated.
