Kalidou Koulialy has announced his move from Chelsea to Al-Hilal.
While the transfer fee has not been disclosed, it's understood the Senegal defender has been sold for £20m.
Koulibaly joined Chelsea last summer from Napoli, signing a four-year deal.
He announced on social media on Sunday evening: "From my first game to my last, it was an honour to wear this badge.
"Last season wasn't the one we wanted, but I want to thank the fans and everyone at the club for your support."
