Liverpool might have beaten Manchester United quite comfortably in the end but a mistake by Alisson embarrassed the goalkeeper and led to a strange stat comparing him to Liverpool's former number ones.
Manchester United were very poor as Liverpool won the game on Sunday 3-1. From the off the Reds dominated as Jose Mourinho's side were set up to defend and hopefully hit their more attacking hosts on the counter.
Liverpool created a number of opportunities with only last ditch defending or a poor final ball keeping them from taking the lead early. Eventually though Fabinho's ball was perfect for Sadio Mane who put them ahead.
It looked like Jurgen Klopp's side would head into half time with a well deserved lead but before the break disaster struck the Anfield side.
On a rare attack forward Romelu Lukaku found himself in space in the Liverpool box and tried to pull the ball back only for Alisson to drop the ball when it looked simple to collect it.
Jesse Lingard took advantage of the mistake and fired United back into the game. It seemed a shock mistake for a goalkeeper so often lauded for how good he is but one stat came about that shocked fans:
Mignolet and Karius were derided over the last couple of years at Anfield and the latter's mistakes in the Champions League were well covered.
The German was moved on in the summer after Klopp paid out a world record fee on Alisson, which was then surpassed by Chelsea and Kepa, and the Brazilian has mainly been lauded for his efforts.
It shows that stats aren't always that telling and it's just a few days ago that the former Roma keeper was the Reds' hero.
Alisson made a huge stoppage-time to keep Liverpool in the Champions League against Napoli last week.
The Brazilian was barely involved at Anfield but when his team needed him, boy did he produce. Mo Salah put Liverpool 1-0 up in the first-half and they should have scored four or five, with Sadio Mane missing a slew of big chances.
It made for a nervy and frantic finish as Napoli substitute Arkadiusz Milik was played through on goal in stoppage time in what was a massive chance for the visitors.
The Poland striker controlled the ball superbly but saw his effort from point-blank range denied by the heroics of Alisson in the Liverpool goal.
