Liverpool continue to put the pressure on Manchester City as a hard-fought 2-0 win at relegation threatened Cardiff moved them back top of the Premier League on Sunday.
Georginio Wijnaldum's opener just before the hour and James Milner's penalty secured a ninth consecutive win in all competitions for Jurgen Klopp's side and moved them two points ahead of City, who have a game in hand, at the top of the table.
City travel to Manchester United on Wednesday in what appears the toughest hurdle left for the English champions to clear and deny Liverpool a first Premier League title in 29 years.
The Reds remain poised to pounce if Pep Guardiola's side fail to pick up maximum points in their remaining four games.
While Liverpool were cruising into a second successive Champions League semi-final in midweek, Cardiff gave their chances of survival a huge boost with a 2-0 win at Brighton to close within three points of safety.
