Willian, who expects us to face similar tests throughout the season, explained how Sarri wants the team to play.
"He likes us to play, to build from the back with possession and he likes great football so that's what we want to do on the pitch," said the Brazilian to chelseafc.com. "We try to keep the ball, keep possession, play fast with one-twos and now we just have to improve ourselves and continue.
"I think we had a good game against Bournemouth, we played against a difficult team. They had 11 players behind the ball and we tried to move the ball from one side to the other. In the first half it was difficult but in the second half we had more space and we scored the two goals.
"When the opponent gives more space it's better for us but we have to adapt because every team now, when they come to Stamford Bridge, is going to play the same way. They will stay there with 11 players so we will have to keep the ball, have patience and move the ball to try and find some space."
