Roberto Firminho was the man of the first half.
First he served Luis Diaz with a nice cross.
Then he cheered up both Harvey Elliot and Trent Alexander-Arnold, who were each responsible for their long-range shots on goal.
Elliot burst into tears after his goal, which was his first in a Liverpool shirt.
Then Firminho lunged forward and scored 4-0 himself.
Before the break, Virgil Van Dijk also headed in a corner.
