Alisson's world-record price tag means there will be a huge weight of expectation on his shoulders this season.
Liverpool forked out £67.5million to procure the goalkeeper from Roma, days after Loris Karius committed another error in the 3-2 friendly win over Tranmere Rovers.
The German will remain at Anfield, however, as it is Danny Ward who has been pushed towards the exit, the Welshman having joined Leicester City in a £12.5m deal.
Jurgen Klopp has spoken in the past about not wanting to become a cheque-book manager and the German has defended the amount spent on his latest acquisition.
“I think it’s something we have to do," he said, per the Telegraph.
"He has nothing to do with the price, we have nothing to do with the price, it’s the market, that’s how it is and we will not think a lot about it.
“It shows the value of goalkeepers, of course, in this moment. We are really happy to have him here now."
It was an essential signing and while there is no comparison between the former Roma stopper and the other options at Liverpool's disposal, it is inevitable that he is going to be likened to the number ones at their Premier League rivals.
How does Alisson compare?
The Daily Mail have done just that and the statistics make for some interesting reading.
David de Gea, who most would argue is the best goalkeeper in the league if not the world, made 115 saves in 37 games last season, equating to 80.3% of the shots he faced.
Petr Cech, who will either be a back-up at Arsenal or may be returning to Chelsea, made 92 saves at a percentage of 64.4%, though he also made six errors leading directly to goals.
Tottenham's Hugo Lloris, who made an error in the World Cup final, saved 86 shots (70.1%) and made five key mistakes.
As for Alisson? In his final campaign in Serie A, he let in just 28 goals in 37 games, a ratio matched by De Gea, but bettered by Manchester City's Ederson, who let in 26.
His distribution is impressive
Alisson made 109 saves at a rate of 79.3% - so a rate just slightly below De Gea.
The obvious comparison with Ederson, who was key to City's title march, is regarding distribution.
Not only are the two compatriots, they now have the best passing stats of all the top six 'keepers, with Ederson completing 78.9% of his passes to Alisson's 85.3%.
It remains to be seen if Alisson has any problems adapting to English football, but on paper, it's very easy to see why Liverpool have sanctioned such a mammoth transfer.
