"On their day this team can beat anyone, I'm convinced about that," McDermott told the Liverpool Echo.
"Manchester City are the bookies' favourites but Liverpool have already shown they can beat them. The 4-3 scoreline at Anfield flattered City that day as Liverpool could have had more goals before they pulled back two late goals.
"The front three are a breath of fresh air. Their pace and skill makes them very difficult to stop.
"The number of goals they have scored this season has been tremendous. They are always a threat.
"It means we're more than capable of going anywhere and scoring an away goal or two.
"It's been a long time since Liverpool have had big nights in the European Cup at Anfield so it's been great to see this season."
