Lee Cattermole has committed his future to Sunderland by signing a new long-term deal to keep him at the club until 2021.
The tough-tackling midfielder joined the Black Cats in 2009 from Wigan Athletic on an initial four-year deal, before signing an extension to his contract in October 2012, keeping him on Wearside until 2016.
The 27-year-old, a former England Under-21 international, has now signed a new five-year deal, committing his future to the club until 2021.
Head coach Dick Advocaat said: “Lee is the controller of the side.
“He is a motivator, a leader and central to the success of our team.
“To know that he will be with us for many years to come is very important to the club.”
Sunderland AFC’s sporting director Lee Congerton added: “Lee is a hugely important part of our team, both on and off the field.
“He has ten years of experience playing in the Barclays Premier League, which is incredible when you consider he is still only 27 years old, and we are delighted that he has committed his long-term future to Sunderland.”
Cattermole made 28 appearances last season and is now just three games shy of 150 for the club.
Having made his professional debut with Middlesbrough in 2005, Cattermole has played a total of 273 senior career games in all competitions.
