The Reds have invested £67 million ($87m) worth of faith in the Brazil global after losing trust in last season's goalkeeping options.
As well as bringing in Alisson from Roma - a move which made the Brazilian the most expensive goalkeeper of all time - Liverpool have also brought in his countryman Fabinho from Monaco, Xherdan Shaqiri from Stoke and Naby Keita from RB Leipzig.
The money Liverpool have spent both this summer and in acquiring Virgil van Dijk last January has been sizeable, but the snipes from Manchester United manager Jose Mourinho suggesting Klopp has joined the big spenders league have been laughable. We've seen the impact he made after arriving in January.
Loris Karius has thanked Liverpool fans for their support after he was applauded in his first appearance at Anfield after a turbulent few months. But it's happened in a game which will, unfortunately, be remembered for a long time. Yes I think it is possible.
"Simon Mignolet and Karius are good goalkeepers but not great goalkeepers".
"But if you asked them: "What does a goalkeeper do?' They couldn't say more than 'catch balls". It is the type of exercise that the leading Premier League clubs...
"He looks cool and calm on the ball and that's what Klopp wants from his goalkeeper, but they were areas that had to be rectified and it looks like majority have been".
Liverpool would score on two occasions moments later.
Liverpool have looked impressive during their preparations for the new season, which they will begin by welcoming West Ham to Anfield on Sunday afternoon.
