Midfielder Lee Cattermole has pledged his long-term future to Sunderland by agreeing a deal until 2021.
The 27-year-old was due to enter the final year of his contract, which expired in 2016, but Thursday’s announcement by the Premier League club has ended any fears of a possible imminent exit, with head coach Dick Advocaat hailing it as a significant boost.
“Lee is the controller of the side,” the Dutchman told the club’s official website.
“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.”
Cattermole moved to the Stadium of Light from Wigan Athletic in 2009 after starting out at Middlesbrough.
A former England Under-21 international, Cattermole has gone on to make 148 appearances for Sunderland, helping the club reach the League Cup final in 2013-14 and safeguard their Premier League status in each of the last two seasons.
A new deal for the combative midfielder has been mooted since the end of last term and sporting director Lee Congerton said: “He has 10 years of experience playing in the Premier League, which is incredible when you consider he is still only 27.
“And we are delighted that he has committed his long-term future to Sunderland.”
