Liverpool thrashed League One Lincoln to set up a Carabao Cup fourth-round tie with Arsenal next week.
Xherdan Shaqiri curled a fine free-kick into the top corner to put them ahead.
Takumi Minamino and Curtis Jones both scored twice as the second-string Reds cruised through - with £41m Diogo Jota one of three debutants in the game.
Tayo Edun pulled one back, Marko Grujic added a sixth for Liverpool, Lewis Montsma scored for Lincoln and Divock Origi got the Reds' seventh.
Liverpool handed debuts to defenders Rhys Williams and Kostas Tsimikas, with former Wolves forward Jota coming on in the second half.
