It has been a summer of dramatically sweeping change across Liverpool's goalkeeping front.
The Reds have splashed out a world-record breaking £65million to land Alisson from Roma to make him the most expensive goalkeeper in football history.
The big-money purchase comfortably dwarfs the £35m Manchester City to sign Ederson from Benfica in 2017.
Hot on the heels of that deal was Danny Ward's move to Leicester. understood to be worth £12.5million.
The Wales international had been primed to be given a chance as the Reds' first-choice ahead of Loris Karius, before the club acted decisively and aggressively to bring Alisson to Anfield.
The writing was on the wall one way or another for Karius after his blunder against Tranmere in pre-season earlier this month.
With Klopp keen to give his German compatriot a shot at redemption after his costly Champions League meltdown, the keeper fluffed his lines and allowed a routine free-kick to spill into the path of Jonny Smith who made no mistake.
Another error against Borussia Dortmund followed, with the player now considering his future on Merseyside.
And what of Simon Mignolet?
The Belgium international's last Premier League start for the Reds was the 2-1 win at Burnley on New Year's Day. The 30-year-old is expected to move on to pastures new this summer after five years at Anfield.
Alisson signs for Liverpool
The £9million signing's record as the most expensive goalkeeper in Reds history has been obliterated by Alisson 's arrival and the Belgian has surely played the last of his 202 games for the club.
It's a new-look goalkeeping department that Jurgen Klopp will be working with this coming season.
Here's how it has all unfolded.
Simon Mignolet
Simon Mignolet hasn't played for the Reds since January's FA Cup exit to West Brom.
The former Sunderland goalkeeper was used primarily for Premier League games last term, with Karius favoured for Champions League matches.
It was a curious rotation policy from Klopp, but the Liverpool manager never understood why the decision was regularly questioned.
“Why do we think number one, two, three is fixed until the end of all days? “ he said back in September.
"I don’t want to bring that in doubt but how can you ask if he’s number one? By the way, it’s not that he shouldn’t be number one.
"If they train bad they don’t deserve a game, but they both train really well, they keep the level really high."
However, by January, Karius was firmly established as the No.1. Mignolet's last Premier League appearance was the 2-1 win over Burnley at Turf Moor.
Mignolet reiterated last month that his long-term Liverpool future will be considered when he returns from holiday after his World Cup exertions.
It is looking like an Anfield exit is on the cards and the Reds will surely entertain offers for the 30-year-old goalkeeper this summer.
Loris Karius
A little under two months ago, Karius was Liverpool's fully-fledged first-choice, about to play the biggest game of his career against Real Madrid in the Champions League final.
Liverpool fans will need no reminding what happened next.
Two horrendous, goal-gifting clangers were dropped - under the effects of concussion - and the biggest night of his sporting life saw him reduced to tears in the bowels of the NSC Olimpiyskiy.
A reprieve was offered by Klopp, but as the spotlight shone brightly in pre-season, Karius was clearly displaying that scars that have reduced the usually flamboyant character's confidence to rubble.
Karius spilled a routine free-kick save into the path of Tranmere's Jonny Smith to gift the newly-promoted side a goal in a 3-2 win earlier this month.
His place as Liverpool's goalkeeper has been taken away from him - by two different shot-stoppers.
Danny Ward was primed to take over the role, but it is Alisson who is now Klopp's entrusted custodian.
After another error against Dortmund, the player admitted his situation was 'not perfect'.
"Of course that's not perfect for me, but I cannot say much more about that either," Karius said. "I do not know that (whether he will leave before the deadline).
"I cannot say what I'm doing right now, there's still some time left."
Danny Ward
It's difficult not to feel for Danny Ward .
The Wales international shunned interest from Huddersfield - after heroically helping them towards the Premier League promised land last summer - and patiently waited for his shot at Anfield.
An early exit in the Carabao Cup in September last year put paid to his hopes of some first-team game time. That would be Ward's only appearance of the campaign for Klopp's Reds.
However, with Karius' confidence at an all-time low this summer, Ward was being positioned as the man to take his shot this pre-season.
That never arrived after Liverpool made their move for Alisson - following information Roma were willing to do business at a realistic price - and secured a blockbuster deal to relegate Ward down the pecking order, once more.
Alisson
The new kid on the block.
Liverpool informed the player's representatives earlier this year that no bid would be forthcoming this summer.
The Reds believed that negotiating with Roma would prove problematic due to the relatively modest £36.9million fee they managed to snare 44-goal Mohamed Salah for in June 2017.
Still, the Reds kept tabs on the Brazil international's situation and he was given his first taste of Anfield on a memorable night back in April. A riotous Reds hammered Roma out of sight in the first leg of the Champions League semi-final.
Liverpool ran out 5-2 winners to all but secure their place in the final, with Alisson largely helpless throughout after he was continually exposed by a Eusebio Di Francesco's high defensive line.
Alisson was given a less intense Anfield experience when Brazil played Croatia in June.
He arrives as the second most expensive footballer in Liverpool history with many hoping that he is long-standing answer to a position that undermined the Reds for so long.
If Alisson solves the goalkeeping conundrum, the sky is the limit for Klopp's fearless Reds.
