Danny Mills admitted Alisson will be missed by Liverpool on Tuesday night but insisted Adrian is a more than able deputy.
The former Leeds United and Manchester City full-back, speaking exclusively to Football Insider correspondent Dylan Childs, claimed the 33-year-old has performed when called upon so far this campaign.
The Reds were rocked by the news Alisson would miss the second-leg of their last-16 tie against Atletico Madrid after picking up an injury ahead of last Tuesday’s 2-0 FA Cup defeat at Stamford Bridge.
Adrian has started the last two games in the absence of the Brazilian, making an error that gifted Willian the opener for Chelsea.
When asked how significant a loss it would prove for Jurgen Klopp going into the midweek game, Mills told Football Insider: “Adrian came in last time and did a fantastic job. You cannot fault him in anyway shape or form for what he did.
“The Champions League game is where it is at, that is the important one. Alisson’s calmness and his ability to play out – he will be missed. That is a certainty.
“He is a fantastic goalkeeper and to turn that tie around you will need all of your players to be on top form. If you have got one missing that is a bit of a disadvantage.
“There might be nothing to do for large parts against Atletico but he needs to be ready when called upon. That is what makes top goalkeepers. Given the option, you would rather have your strongest goalkeeper.”
Adrian has made 17 appearances for the Reds so far this season, including a match-winning performance against Chelsea in the UEFA Super Cup in August.
