Chelsea solidified their place in the Premier League's top four by beating Tottenham 2-0 on Sunday as Liverpool cut the gap on Manchester City at the top to nine points with a 3-1 win at Crystal Palace.
A third defeat to Chelsea in the past month cost Spurs the chance to move into the top four and Arsenal also blew that opportunity as they were held 0-0 at home by Burnley.
Chelsea had won just one of their previous seven league games to fall out of contention for the title.
The Blues went into the weekend looking over their shoulder at the chasing pack for a place in next season's Champions League, but opened up a 10-point advantage over fifth thanks to two goals in eight minutes at the start of the second half.
Spurs felt aggrieved when Harry Kane had a goal ruled out just before the break for a push on Thiago Silva.
But they had no response after Hakim Ziyech opened the scoring with a stunning strike into the top corner on 47 minutes.
Silva then headed in Mason Mount's free kick to repeat the scoreline at Stamford Bridge when the two sides met in the League Cup semifinals earlier this month.
Chelsea close back to within a point of second-placed Liverpool, but have played two more games than the Reds.
Jurgen Klopp's men kept hope of a Premier League title race alive with a roller-coaster 3-1 win at Selhurst Park.
The visitors blew Palace away in the opening half hour before being forced to hang on in the second half.
Virgil van Dijk's towering header from Andy Robertson's corner opened the scoring just eight minutes in.
Robertson was the creator again when Alex Oxlade-Chamberlain doubled Liverpool's lead with a calm finish.
However, Liverpool ended up relying on goalkeeper Alisson Becker to come away with the win.
The Brazilian made brilliant saves from Michael Olise, Jean-Philippe Mateta and Odsonne Edouard either side of halftime, while Conor Gallagher headed a glorious chance wide.
Palace finally got their reward with a brilliant move as Jeffrey Schlupp and Mateta teed up Edouard for a tap-in.
But Liverpool's two-goal cushion was restored in controversial circumstances a minute from time when a penalty was given after a lengthy VAR intervention for Vicente Guaita's block on Diogo Jota.
