David de Gea has signed a new contract at Manchester United until 2023, which includes an option for a further year.
De Gea, the 28-year-old goalkeeper who joined United from Atletico Madrid in 2011, has won the Premier League, the FA Cup, the League Cup and Europa League since moving to Old Trafford.
The deal - which will see the Spain international earn between £350,000 and £375,000 per week - makes De Gea the world's highest-paid goalkeeper, Sky Sports News understands.
"It has been a privilege to spend eight years at this great club and the opportunity to continue my career at Manchester United is a genuine honour," said De Gea.
"Since I arrived here, I could never have imagined I would play over 350 games for this club. Now my future is fixed, all I want is to help this team achieve what I believe we can and win trophies again, together.
"I am committed to continue repaying the fans for all of the care that they've shown me during the good times and the bad."
United manager Ole Gunnar Solskjaer added: "I am delighted that David has committed his long-term future to the club.

Over recent years, David has proved himself to be the best in the world and a vital part of our plans as we look to take Manchester United back to where it belongs.
"David is a fantastic person and his outstanding quality provides the perfect base to our defence. Over his time here, David has really understood the values of playing for Manchester United and now represents everything you want in a goalkeeper.
"As a player he is still hugely determined and hungry to achieve more. We all look forward to working together to meet those ambitions over the coming years."
Nev: De Gea can settle down now
Sky Sports pundit and former Manchester United captain Gary Neville:
'De Gea has had a difficult time in the Premier League and he's had difficulties at home where he's lost his place in the national team. I don't think he's fully recovered from the poor World Cup in 2018, and he's made more mistakes in the last 15 months than ever before.
'But I've got to believe that this is good news and hope that what's happened in the last 12 to 15 months has been a result of the ongoing speculation. The hope is that now he's signed, he can settle down and start performing.
'United need a spine. They had eight academy players in the squad on Saturday, but their problem isn't the academy. The problem is that they haven't got a strong, dominant spine, but De Gea can be the start of that.'
Analysis: Real boost from De Gea deal
Sky Sports News North West correspondent James Cooper:
'It's a real boost and it's a real positive step in the right direction - one that Manchester United fans have been clamouring for. It's a big tick in the box for Ole Gunnar Solskjaer and it's a vote of confidence in the Manchester United manager to show that he is here for the long-term.
'Solskjaer is here to complete what people are calling a reboot at Manchester United. If we look at the geography of the negotiations, they've been going on for the last couple of years. They've always been confident that they would reach some sort of deal.
'When you think that David de Gea is 28 years old, and is one of four players in the squad that have won the Premier League in the red of Manchester United, it says an awful lot about the club that they've managed to secure his services.'
