Alisson's move to Liverpool reunited him with Mohamed Salah, who left Roma for Liverpool this time last summer. Liverpool have been dogged in their pursuit of the player following the conclusion of the World Cup.
The signing of German Loris Karius was supposed to ensure a stable pair of hands between the sticks, but his deficiencies have been exposed time and again too, none more than the two blunders he made in the UEFA Champions League final against Real Madrid.
At over £30m more than what was spent to recruit last season's star, Salah, from the same club, it seems Liverpool have set a new benchmark for record spending which even they may find hard to justify.
Known as "goleiro gato" in Brazil - literally "handsome goalkeeper" - Alisson has refused modelling work and even rejected claims that his good looks have accelerated his progress.
There was a world-class goalkeeper on the market, and the club gave us the opportunity to sign him.
"It shows the value of goalkeepers, of course, in this moment".
Reflecting on that semi-final first-leg, Alisson said: "I think it was one of the tensest games of my career and one of the most exciting".
Alisson made 109 saves at a rate of 79.3% - so a rate just slightly below De Gea.
It is hard to divorce goalkeeping statistics from the defences they play behind, so it is not worth stewing over clean sheets or goals conceded. "We met again in the game when we were up against each other [in the Champions League in April]", Alisson added.
On whether or not he cut his holiday short, the Brazilian said: "Yes, I did cut them short a bit but I was immensely satisfied to do so, to make this dream come true and take the next step in my career". I don't think many people have realised who Alisson is.
