Liverpool signed Brazil's Alisson from AS Roma on Thursday making him the most expensive goalkeeper ever in the process.
The Serie A side said Liverpool had agreed a deal worth up to €72.5 million for the 25-year-old, eclipsing the previous record of €53 million paid by Juventus for Gianluigi Buffon in 2001.
Naby Keita, Fabinho and Xherdan Shaqiri are the other players to have already joined in what appears a concerted move to transform the perennial Premier League underperformers into genuine title contenders.
Liverpool were the only club to score against him in the Champions League at the Stadio Olimpico last season, striking twice in a 4-2 semifinal defeat but progressing to the final.
Monchi confirmed that Alisson is now in Liverpool, saying "Alisson is in Liverpool and we're at a very advanced stage, but the deal is not done yet".
Chelsea have also been linked with Alisson who began his career with Internacional before moving to Roma two years ago.
A bonus for LFC fans is Monchi's ringing endorsement of Alisson as he nears the exit, saying: " Alisson is a top player, perhaps the best goalkeeper in the world".
"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".
"[The owners] were quite excited, so we did it", the Reds boss told his club's official website.
Upon the arrival of Jurgen Klopp, the tactician placed his faith in Loris Karius as the No.1, but his mistakes in the Champions League final against Real Madrid has all but sealed his fate at the Anfield club.
'We have everything we need for the next season, because I don't think we will do anything more.
