Chelsea maintained its 9 points lead at the top of the Premier League table following Saturday’s 3-1 victory over Arsenal at Stamford Bridge.

Chelsea goalkeeper Thibaut Courtois says Antonio Conte’s relentless training demands is the secrets to Chelsea’s success this season.

“It’s good if you have a manager who is demanding a lot,” the 24-year-old goalkeeper told Sky Sports.

“You have to be at your top every week, and that’s what makes you champion. If you have a manager who is not demanding then sometimes you relax and you lose games.”
