Virgil van Dijk gave a timely boost to Liverpool on the eve of their first Premier League match of the season with newly-promoted Norwich City by signing a new long-term contract, the club announced on Friday.
The 30-year-old Dutch international central defender's new deal is reported to tie him to the club till 2025.
Van Dijk's absence due to a knee injury suffered in the Merseyside Derby with Everton last October cost Liverpool dear in their defence of the title last season and also saw him miss Euro 2020.
He is the fourth senior Liverpool player to extend his contract in the last couple of weeks after England defender Trent Alexander-Arnold and Brazilian duo Fabinho and Alisson Becker.
"If you're a real Liverpool fan you're excited about the news the club delivered in the last few weeks," said Liverpool manager Jurgen Klopp at his Friday press conference.
"Allison's new contract, same with Trent Alexander-Arnold, Fabinho and Virgil Van Dijk. Others will follow, so that's great.
"It's not as spectacular (as new signings by their rivals) but it's great news - if other teams wanted to sign these players they'd have to pay a lot of money and we have them already."
Van Dijk signed from Southampton in 2018 for a reported £75 million and was pivotal in Liverpool winning the 2019 Champions League and the Premier League the following season.
"Amazing. It is something to be very proud of, that I am very proud of, that my wife and my kids are very proud of," he told Liverpool.com.
"All the hard work we've put in so far continues and I am looking forward to what the future brings together with Liverpool.
"I'm delighted, very happy and proud."
The Netherlands captain has made 130 appearances for the club, scoring 13 goals, and has also collected winner's medals in the UEFA Super Cup and FIFA Club World Cup.
Individually, he was voted the PFA Players' Player of the Year (2018/19), UEFA Men's Player of the Year (2018/19) while he was runner-up in the 2019 Ballon d'Or and The Best FIFA Men's Player in 2019.
"Since day one when I joined the club, I felt so much appreciation from the fans and from my teammates and the staff, that I could be a very important member of this football club," said van Dijk.
"It has been going well. Unfortunately last season for me personally has been a season to forget, to learn from and take with me, but I have enjoyed my time here and will keep enjoying it in the next couple of years altogether with all of you."
