The Brazilian left Stamford Bridge for North London in a shocking transfer deadline day move for a fee around £8 million just two months after the club broke protocol to give him a two-year contract extension.
Following the arrival of Frank Lampard as the Blues’ head coach, Luiz was told he would not be an automatic starter by the former Derby County boss after a conversation was held between the two.
The former Paris Saint-German man said he was happy at Chelsea but he had to take a swift decision after realizing he would not be part of Lampard’s plan.
"First of all, I was always very happy at Chelsea,” Luiz told ESPN Brazil.
“And then the understanding of knowing that my cycle was over, even though I thought it wasn't going to end that way, in a quick decision.”
“I decided to leave Chelsea before I even had my doors open at Arsenal. I know that Arsenal did not come at a great moment, they are heavy on defence, I will go there and I will have to pay the restaurant bill without having eaten.”
“But I am going because I want something new for my life, I want to learn.”
“It was not easy at first. Not only of adaptation, but withstanding the criticism, the sadness of many Chelsea fans for not understanding my personal decisions. My respect and love for Chelsea has always been true.”
