Liverpool manager Jurgen Klopp insisted he was "really happy" Alisson had made his first mistake for the club after the goalkeeper's howler against Leicester City.
The Brazil shot-stopper was dispossessed by Kelechi Iheanacho and saw his team concede their first goal of the Premier League season during their 2-1 win on Saturday.
Alisson, 25, had impressed in his opening games for Liverpool, the club he joined from Roma in a reported £66.8million deal in July.

"He is 0.0 per cent arrogant, but he's confident and he can do it. It's like when our centre-halves play passes," he said.
"They have to play passes and defend and all that stuff. I don't look for anyone responsible, the final one was Alisson but we should have cleared the situation before.
"It wasn't a situation where you pass the ball back. We make decisions in a second and in a second you realise, 'That was the wrong one'.
"I think that was this situation. To be 100 per cent honest I am really happy it happened, because we don't have to wait for it now."
Liverpool are top of the table heading into the international break, with their next outing a trip to Tottenham on September 15.
