While the scoreline was heading towards something even uglier, once the Reds were up 4-0 at half-time, Norwich did well to show us what they're capable of, and even score a goal in the 2nd half through Teemu Pukki, who was so crucial in their promotion campaign last season.
With Alisson ruled out of Wednesday's UEFA Super Cup clash with Chelsea and facing a longer layoff, Van Dijk believes that former West Ham shot stopper Adrian has the quality to step up and perform for Juergen Klopp's team.
Jurgen Klopp has confessed he is anxious goalkeeper Alisson could be set for an extended spell on the sidelines after suffering a leg injury during Liverpool's 4-1 win over Norwich City on Friday.
The Brazilian was substituted with a calf injury in Liverpool's opening Premier League fixture against Norwich City.
He said: "The Ali situation is a shadow on that game, it's clear".
Alisson started every Premier League match last season and generates attacking moves with his ability to pass out from the back.More news: A U.S.-China Currency War? What You Need To Know

Though Wednesday's match is an inevitable reminder of Liverpool's status as European champions, Klopp is determined to focus on the future.
Liverpool was gifted an opener seven minutes into season when Grant Hanley deflected Divock Origi's cross into his own net.
"That means it's probably a bit more than a strain, we have to see, we make the diagnosis in the morning, we don't know exactly, but it doesn't look too good".
After Liverpool had to change its goalkeepers - with Alisson replaced by Adrian - Krul conceded again before halftime when Origi slipped his marker to meet Trent Alexander-Arnold's cross. The Spaniard came on in relief of Alisson against Norwich, and perhaps could have done better on Pukki's goal.
"But it's the first game of the season - there's going to be things that we need to improve on, look back on and work on".
Klopp added that he was pleased with the win but insisted his team should have taken control of the game more in the second half.
