Alisson has revealed how last season's Champions League trip to Anfield lit the fuse for what has become a world-record transfer to Liverpool.
The 25-year-old goalkeeper penned a long-term contract with the Premier League side on Thursday after Roma agreed to sell him for an initial £56 million ($73m) fee.
That price confirmed his status as the most expensive keeper of all-time and could yet rise a further £9m depending on performance-related clauses.
Jurgen Klopp described the Brazil international as "one of the world's best" despite seeing his side put seven goals past him over the two legs of last season's Champions League semi-final.
