Chelsea midfielder Ramires has signed a new five-year contract to remain at Stamford Bridge.

The hard-working Brazil international joined the Blues from Benfica in the summer of 2010 and has since established himself as a key part of the midfield.

"I am very happy with my new contract. I am very happy with the support I have playing for this club so I want to say thank you to Chelsea," he told the club's official website.
