The 32-year-old Republic of Ireland international has become a key player since joining the London club from Newcastle in August 2009, helping the Cottagers reach the 2010 Europa League final. Duff put pen to paper on his new deal on Friday and believes there will be many more good times ahead under new manager Martin Jol. He told the club's official website: "I've enjoyed every minute of my time at Fulham since joining two years ago and I'm delighted to be staying at the Cottage until at least 2013. "This is a fantastic club with great supporters and it's a very exciting time to be part of the team. "I feel in great condition and I'm hungry to achieve more success for this club. "We've had some great moments together so far and I believe there's more to come from us in the Premier League and Europe this season under Martin Jol." Duff began his senior career at Blackburn, winning the League Cup with Rovers in 2002 before switching to Chelsea the following year. He won two Premier League titles and another League Cup during a three-year stint at Stamford Bridge before signing for Newcastle, where he spent a less successful three years prior to his transfer to Fulham. The Cottagers confirmed news of Duff's new deal in a statement on their website this afternoon, a day after he had helped Jol's side defeat Ukrainian outfit Dnipro 3-0 in the first leg of their Europa League play-off. It read: "The club can confirm that Damien Duff has signed a one-year contract extension that will see Fulham's Republic of Ireland international remain at Craven Cottage until at least the summer of 2013. "Duff joined Fulham in August 2009 from Newcastle United in a move that has revitalised his career after a frustrating spell on Tyneside. "The winger regained his form and fitness to become an integral part of the team's success over the past two seasons, including Fulham's remarkable journey to the 2010 UEFA Europa League final. "Regulars at the Cottage will testify that the signing of Duff has turned out to be an inspired piece of business by the club and both parties are delighted to confirm the news that the player will remain at the Cottage for at least the next two seasons."
