Willian is ready to fight his way back into the Chelsea first team.
Willian insists he is ready to return to Chelsea's starting line-up following the recent death of his mother.
"The manager changed the team because I was in a difficult moment. I lost my mum and I had to stay in Brazil for a few days," he told Sky Sports.
"I missed some games and the team started to win and play well. Pedro came in and he did very well.
"But the manager talked to me and told me to stay concentrated, to work hard in training and when I come into the game to try to do my best. I feel more fresh and good to come back in the team.
"He gives me confidence to get back in the team and train hard to play well. I am happy because I came in and helped my team-mates to win that game (against Man City).
"Sometimes the game is asking to change some things, to put in another player and change the system. The players on the bench have to be focused because, when you go in, you have to do something different."
