Liverpool secured a 2-1 win against Brighton and Hove Albion on Saturday to extend their lead on the Premier League table to 11 points despite having goalkeeper Alisson Becker sent off.
Defender Virgil van Dijk scored two towering headers from Trent Alexander-Arnold set-piece deliveries to put Liverpool 2-0 up inside 25 minutes.
However, Alisson was sent off 14 minutes from time for handling outside his area and Brighton reduced the deficit after captain Lewis Dunk powered the resulting free-kick past substitute goalkeeper, Adrian.
But the 10 men held out for another vital three points to edge closer to a first league title in 30 years.
Elsewhere, Tottenham Hotspur grabbed their third consecutive win under manager Jose Mourinho after surviving a late fightback by Bournemouth to secure a 3-2 win.
Dele Alli scored a brace on either side of half time as he led Spurs to what was going to be a comfortable win.
Toby Alderweireld’s raking pass created Alli’s opening goal, with the England midfielder racing on to Son Heung-min’s touch to tap the ball past Cherries goalkeeper Aaron Ramsdale.
Alli’s second came from the same source, as he superbly controlled Alderweireld’s pass before holding off Jack Stacey and flicking the ball over Ramsdale.
Moussa Sissoko added Spurs’ third goal – with a close-range volley from Son’s exemplary cross.
However, Harry Wilson’s introduction sparked the visitors into life, pulling one back with a superb free-kick.
The on-loan Liverpool midfielder reduced the arrears further six minutes into stoppage time, although it proved too little too late for the Cherries.
Meanwhile, Chelsea missed the chance to go level on points with second-placed City as Frank Lampard’s men suffered a shock 1-0 home defeat by West Ham.
Defender Aaron Cresswell’s right-footed strike inside the Chelsea penalty area in the 48th minute gave West Ham and manager Manuel Pellegrini a much-needed win after going through a seven-game winless streak.
Cresswell dummied a Chelsea defender and fired low past Kepa Arrizabalaga.
The visitors also thought they had gone 2-0 up after 71 minutes, but Michail Antonio’s goal was ruled out for handball.
Victory lifted West Ham six points clear of the relegation zone while Chelsea failed to close the three-point gap to second-placed Manchester City and Leicester City in third.
