England captain Jamie Peacock on Friday signed a new two-year contract with Super League champions Leeds. Peacock\'s current deal was due to expire at the end of the year, but the 33-year-old will now stay with the Rhinos until the conclusion of the 2014 campaign. \"I am really confident that the sports science that we now employ in training means that I can maintain my high standards and make a contribution to the team until 2014,\" he said. \"As a player the important thing is that you are working hard for yourself and to do that in the right team and the right environment. \"My hunger for success is still as huge as ever as that is important. It is not just the body that needs to be strong, your mind needs to match that burning desire to succeed and I still have both of those qualities.\" Peacock is one of the sport\'s most decorated players, having won a record seven Super League Grand Finals and four World Club Challenge titles. He was awarded an MBE in the New Year Honours List for services to rugby league and will captain England in the mid-season Exiles series. Leeds coach Brian McDermott said: \"Jamie is one of the true stars of our game and I am delighted he has agreed a new deal that will see him finish his career at his home-town club. \"To have played at the highest level for your entire career, regularly peaking at your best for the play-offs and Grand Finals at the end of the season, shows the stamina, determination and will to win that has become his trademark down the years.\"
