Roberto Firmino sent Fabinho a message prior to him putting pen to paper with Liverpool - and it convinced him to sign.
Brazilian Firmino knows Fabinho from his country's international set up and was integral to Liverpool getting their man back in 2018.
Jurgen Klopp signed the midfielder from Monaco very early on in the summer 2018, just days after Liverpool's Champions League final defeat by Real Madrid .
Fabinho penned a five-year deal after the £43.7million transfer fee went through, and revealed his delight in signing for the Anfield giants.
The Reds had chased Fabinho since the 2012/13 season, when he spent a season at Real Madrid on loan from Rio Ave.
But it was a conversation with striker Firmino, who joined Liverpool in 2015 from Hoffenheim, that persuaded him to move to Merseyside.
"This manager demands a lot but he will improve you," Firminho told Fabinho, according to The Athletic.
Firmino, along with fellow Brazilian Alisson and his wife Rebeca, were also integral for keeping the defensive midfielder's spirits up during a frustrating first season at Anfield.
Fabinho was used sparingly during his debut campaign, especially in the Premier League where he only made 28 appearances.
Klopp has already got onto the pitch in all three of the Reds' league matches this season, along with starting both the Community Shield and UEFA Super Cup.
Against Arsenal at the weekend, Fabinho ran the Reds midfield to help set-up a 3-1 victory over the Gunners - with Joel Matip and a Mohamed Salah brace settling the three points.
Klopp in particular was thrilled with Fabinho's display, branding it "sensational", before adding: “There was one tackle from him that was just incredible – completely clean, winning the ball and passing it with his bum pretty much still on the floor!”
