“Always I say that I want to stay at Chelsea as long as possible, and I am happy to stay here.
“When I arrive here my plan was to stay here as long as possible and now I am here five years I hope stay five more!
“I know I have two years of contract left but I hope to stay more years in the Premier League.
“I am very happy to be here five years. I have won titles and played a lot of games with a lot of happy moments, and a few sad moments as well but that is part of football.
“But these five years have been very good for me and I am proud to be a Chelsea player.” Willian said.
