Fabinho has completed his move to Saudi Arabian club Al-Ittihad.
The 29-year-old Brazilian midfielder has agreed a three-year deal after the £40m transfer fee was accepted by Liverpool.
“I say this with a heart full of joy: I love this club. Thank you, Reds, for everything we’ve experienced together,” he said.
Fabinho made 219 appearances for Liverpool, scoring 11 goals, after joining from Monaco five years ago.
During his time at the club he helped them win the Premier League, Champions League, FA Cup, League Cup and Fifa Club World Cup.
