Arsenal confirm that William Saliba signs new long term deal valid until June 2027.
The 22-year-old defender has put pen to paper on a deal. His salary will be £10million a year and his deal has no release clause.
The terms do not include an option to extend but, in keeping with other Arsenal contracts, there is no release clause.
The France international's previous contract was scheduled to expire in 2024 and, given Arsenal had activated an option to take it that far, there was no provision for a further extension.
But the north London side have now secured his services for longer, amid strong interest from other teams in the Premier League and abroad.
An announcement is expected to come on Friday.
Saliba was a key player last season as Arsenal challenged for the Premier League title. He missed the last 11 games of the season through injury, which coincided with a drop in form and saw Mikel Arteta's side slip from the top of the table behind eventual champions Manchester City.
Saliba follows his team-mates Bukayo Saka, Gabriel, Gabriel Martinelli and Aaron Ramsdale in signing a new contract with the north London side.
Saliba joined Arsenal from French side Saint-Etienne in 2019 but spent significant spells out on loan. He returned to Saint-Etienne for the rest of the 2019-20 season. He spent the first half of the 2020-21 campaign with Arsenal before moving to Nice in January.
He then had a season on loan with Marseille before returning to Arsenal last summer. Saliba played 27 times in all competitions as Arsenal missed out on the title but qualified for the Champions League.
"I was born in north Paris, but became a man in north London." He said.
Mikel Arteta on William Saliba:
“To have William extend his contract with us was something we have wanted to do for a long time.
“William proved last season just how good and how important he is to our squad.
“The ability he has at his young age of just 22 is exciting, and there is of course so much more room for development with any player at this stage of their career.
“We’re looking forward to continuing to work with William in the years to come.”
