Liverpool crushed Tottenham Hotspur 4-0 at Anfield to overtake Chelsea at the top of the Premier League table.
They are two points ahead of Chelsea with a much better goal difference and four clear of Manchester City, who have two games in hand.
City and Chelsea, who both dropped points on Saturday, still have to visit Anfield.
Liverpool, who have not won the English title since 1990, went ahead after two minutes with an own goal by Spurs defender Younes Kaboul and doubled the lead through Luis Suarez's 29th goal of the season in the 25th.
Brazilian Philippe Coutinho scored the third after 55 minutes and Jordan Henderson completed the rout quarter of an hour from the end.
Tottenham's hopes of finishing fifth were further diminished by Everton's 3-1 victory over Fulham in the day's earlier game.
Everton score three
Everton improved their outside chance of snatching a Champions League place next season by winning 3-1 away to bottom of the table Fulham.
Victory put them four points behind fourth-placed Arsenal and four clear of Tottenham Hotspur, who face a tough task away to Liverpool in the day's late game in the Premier League.
Scottish international Naismith, made the opening goal after 51 minutes with a shot that was being deflected wide until it struck goalkeeper David Stockdale and trickled over the line.
Fulham continued to press and scored a deserved equaliser in the 71st minute.
Iranian international Ashkan Dejagah, who had come on for Richardson, cut inside from the left and hit a scorching shot from the edge of the penalty area.
Two substitutes then combined for Everton's second goal, Aiden McGeady sending Belgian international Kevin Mirallas through to score with 11 minutes left.
Steven Naismith completed the scoring to leave Fulham and their German manager Felix Magath deflated after his team had had the better of the first half's play.
Even a draw would have taken the London side off the bottom of the table, but their chances of avoiding relegation are looking thinner by the week.
