David Luiz is delighted with the way he has settled at Chelsea.
Luiz insists language is not a problem at his new club.
"The language doesn't get in the way at Chelsea," he said. "I have been taking English classes but the language isn't a problem.
"Everything has been very positive since I signed and I am very happy for this opportunity that God gave me to play at Chelsea.
"I have to keep my concentration and focus to become a better player in the future.
"As for Chelsea, we are still fighting for the title and the Champions League."
