Chelsea midfielder Ramires has signed a new four-year deal at Stamford Bridge, the club have confirmed. The Brazil international, who joined the Blues from Benfica in 2010, has recently been forced to deny claims of a mutiny breaking out against under-fire manager Jose Mourinho and has now given the strongest possible indication of his own happiness in signing a new deal.

"I am very happy to sign a new contract with Chelsea," Ramires told the club's official website. "My family and I are very happy here in London and in the past five years the club has lifted every major trophy. I hope to be an important part of many more successes in the next four years."

Ramires has been outspoken in his attempts to dismiss suggestions of discontent among the Chelsea ranks during their miserable start to the Premier League season. The club have lost five of their 10 league games so far this season with the London Evening Standard suggesting the club's dire form has left Mourinho unable to control an increasingly unhappy dressing room.

Ramires, who has featured frequently under the Portuguese either in a central midfield role or on the wing since the manager's return to West London in 2013, rubbished such claims, however.

"There is no mutiny against Mourinho," Ramires confirmed to ESPN Brazil, as relayed by The Independent. "If you take our last games you will see how everyone is running relentlessly, putting their lives on the line on the pitch, as we say.

"Whenever we're under bad form, it's only natural that negative speculations will arise, but the whole group isn't paying attention to the outside and we're focused on doing what Mourinho asks us to do and, consequently, help Chelsea to get back on the winning track."
