Liverpool's Premier League title defence got off to a perfect start through three games, but the excitement from last season's triumph wore off very quickly as the Reds were exposed by Aston Villa.
Villa fired four goals past Liverpool's highly-regarded backline in the first half, continuously beating the Reds' backline through 45 minutes before adding another goal just a few minutes into the second half.
The Reds' high line was exposed time and time again, with Ollie Watkins netting a first-half hat-trick within 39 minutes.
He was joined on the scoresheet by John McGinn, with Mohamed Salah scoring at the other end to give Liverpool at least one positive moment from the first 45 minutes.
