Virgil van Dijk was also on the scoresheet with Jack Harrison, Patrick Bamford and Mateusz Klich getting the goal for Leeds.

“There’s nothing wrong with Liverpool going forward, and you could see that today,” Allardyce told talkSPORT.

“Liverpool last season had the best defensive record in the league.
