Chelsea goalkeeper Thibaut Courtois has branded manager Antonio Conte's training sessions "boring".
Conte compiles tactical videos for his players to study.
Courtois said: “We worked on that a lot and maybe that is sometimes boring.
“But it's important to know how to do these things.
“In terms of food, drinks and everything, he put a new regime in place.
“In training, he wanted to put his mark on the group immediately, with videos to see how we would have to train and work, what we do well and tactically what to do."
