Al-Hilal have signed Ali Al Habsi from Championship side Reading.
The Oman international has signed a three-year deal with the Saudi champions.
The Saudi Pro League champions, who won their 14th title last season, have secured the services of the former Wigan Athletic player.
The 35-year-old made 91 appearances for Reading who made the Championship play-off final under Jaap Stam last year.
"It was surely a tough decision to take," Al-Habsi said on Twitter after Al-Hilal triggered his release clause.
He had signed a new deal with Reading until 2019 in January but has decided to join the Saudi outfit.
Al-Habsi added: "I have spent a great two years at Reading. It was a one of a kind experience.
"I am sure Reading will do great next season, especially with a perfect manager like Jaap Stam, you will push forward and will have excellent results."
