Excellent stop from Mara as Southampton threatened constantly early on and another fine save denied Sulemana second half. Supremely confident should

Conor Bradley 7

Struggled to make much impression going forward in opening quarter and hands full with Sulemana but much better after that. Shot forced the third goal.

Jarell Quansah 7

Gave away one ball in a dangerous position and beaten by Sulemana for one opportunity. One of many to improve markedly second half, with some good long distribution.

Virgil van Dijk 6

Appeared to still be celebrating his Wembley winner during a very strange opening before settling. Subbed.

Kostas Tsimikas 7

Probed forward regularly but positionally wayward at times, but tightened that up in second half and crossing began to cause problems for Southampton

A goal for debutant Lewis Koumas and two from teenage substitute Jayden Danns earned a 3-0 fifth-round win over the Championship side at Anfield on Wednesday evening.
