Working under manager Antonio Conte is a complete new experience, striker Michy Batshuayi has revealed.
The Belgium international was Conte's first summer signing after joining from Olympique de Marseille.
He featured and scored against Atus Ferlach as he declared that he is progressing well at Stamford Bridge.
"It's been really, really good [so far at Chelsea],' he told the club's official website.
"Everyone in the group has made me feel at home, and everyone has helped me so much, the players and the backroom staff too. Even people who don't speak French have tried for me. There is a great atmosphere here.
"I have a perfect relationship with the coach as well.
"I already feel like I am progressing a lot under him. I am still young, 22, and I am happy to have a great coach who will make me improve.
"Training has been very tactical and very physical, it's been on another level. It's been different to what I experienced before because you have to be 100 per cent concentrated in every session."
