Fabinho has completed his move from Liverpool to Al-Ittihad, the Saudi Pro League club have confirmed.
The Brazilian is the second Liverpool player to move to Saudi Arabia following Jordan Henderson's switch to Al-Ettifaq.
In a lengthy farewell message posted on social media, Fabinho wrote: "Today I leave my home.
"It’s been five years wearing this jersey and always with the greatest honour and happiness possible."
Liverpool, who are understood to be pursuing Southampton midfielder Romeo Lavia, also confirmed the move on their club website.
"Fabinho has today completed a permanent transfer to Al-Ittihad after five years with Liverpool FC,"
"The Brazilian midfielder finalised the switch to the Saudi Arabian club, bringing an end to a memorable spell at Anfield that included 219 appearances in all competitions and five major honours.
"Signed from AS Monaco in May 2018, Fabinho broke into Jürgen Klopp's starting line-up several months into his first season and would become a fulcrum in the Reds’ sustained success in the years that followed."
