Glen Johnson has signed a contract extension at Liverpool.
Johnson, 26, signed for Liverpool from Portsmouth in 2009 and has gone on to make 70 appearances for the club.
Liverpool director of football Damien Comolli told the club's official website: "We are absolutely delighted. We were in talks for a few weeks, but it was easy to find an agreement because he wanted to stay and we wanted him to stay.
"We are very pleased he wants to commit long term, and I think he was pleased we went to him and asked him to commit long term.
"His best years are to come. Very often defenders peak between 26 and 31, so he is just entering into those years where a maturity comes in and his knowledge of the game gets better and better. We are happy his long-term future is at Liverpool."
He added: "It's obvious when you watch him play his technical ability is second to none. Physically he is absolutely fantastic as well and his fitness level is great.
"Towards the end of last season he showed how versatile he is by playing at left-back or right-back - mostly at left-back - and was outstanding.
"For us he is a great asset to have around. As we've always said, we don't want to sell our best players or sell our assets and as long as the players are happy to be here, we're happy to commit to them."
The length of the extension has not been revealed.
