British media reported that Al-Ettifaq would pay about 12 million pounds plus add-ons for Henderson, who will end his 12-year stay at Anfield.

He will receive a weekly salary of around 700,000 pounds, according to British media.

Henderson bid farewell to Liverpool fans in a video posted on social media on Wednesday.

"It's hard to put these last 12 years into words and it's even harder to say goodbye. I will always be a Red. Until the day I die. Thank you for everything. You'll never walk alone," he wrote on his Instagram account.

Henderson will be reunited at Al-Ettifaq with former Liverpool teammate Steven Gerrard, who was appointed coach on a three-year contract at the beginning of July.

Henderson arrived at Liverpool in 2011 from Sunderland and was made captain following Gerrard's move to Los Angeles Galaxy in 2015.

Henderson played nearly 500 games for Liverpool in all competitions and won the Premier League and Champions League as well as the FA Cup, two League Cups, the Club World Cup and UEFA Super Cup.

Henderson's move to Saudi Arabia, where homosexuality is illegal, has made headlines as he is a vocal advocate for LGBTQ+ rights and a supporter of Stonewall's Rainbow Laces campaign.

"Once again, our existence and the concept of 'allyship' towards us is feeble in comparison to a vast paycheck," 3LionsPride, a group representing England fans, stated before Henderson's announcement was made official.

"The ability to say the right words when they are easy and abandon them when money talks or times get tough is exactly why the term 'ally' is outdated and ineffective."

Al-Ettifaq finished seventh in the top-tier Saudi Pro League last season.
