Speaking to his new club's official website, the goalkeeper expressed his excitement at reuniting with former Roma teammate Mohamed Salah, while admitting he was influenced in part by the Reds' 5-2 victory over the Giallorossi at Anfield last season.
The 25-year-old travelled to England on a private jet on Wednesday evening and will undergo a medical with the Reds in the next few days.
He has been at Roma for two years, and played 37 Serie A games in 2017-18.

Of course, for a club whose entire fan base remains traumatised by the performance of their goalkeeper in June's Champions League final, none of that really matters.

"How we all do, he needs to adapt to the English Premier League, that's how it is".
Having spent his first season as understudy to Wojciech Szczesny at the Stadio Olimpico, Alisson only broke through as Roma's first choice in goal last season, following the departure of his Polish counterpart to Juventus last summer.
"Liverpool FC needs just the highest quality goalkeepers and that's what we have at the moment, we'll see now what we do in the next few weeks".
