London: Eden Hazard's brilliant goal in Chelsea's 3-1 victory over Arsenal further buried the title hopes of their Premier League rivals with even angry Arsene Wenger admitting that his London foes are a class act.
Antonio Conte's side shattered Arsenal's hopes while Jurgen Klopp's Liverpool hit a new low in a 2-0 defeat at Hull in Saturday's games.
Belgian winger Hazard picked up the ball in his own half and waltzed past four opposing players to shoot home at Stamford Bridge after Marcos Alonso opened the scoring with a contentious effort, clattering into Arsenal's Hector Bellerin before heading home.
Cesc Fabregas rubbed salt into Arsenal's wounds in the 85th minute when the former Gunners midfielder chipped into the empty net after a woeful miskick from ex-Chelsea goalkeeper Petr Cech.
Olivier Giroud got a consolation but third placed Arsenal trail Chelsea by 12 points with 14 games remaining.
Chelsea have 16 wins in their last 18 league games, prompting Conte to hail the triumph as a significant moment in the title race.
"I consider Arsenal one of the six teams that can fight for the title. To put them 12 points behind is very important for us," Conte said.
Wenger fumed over Alonso's opener, saying: "It was 100 percent a foul. It was even dangerous play."
But he joined Manchester City's Pep Guardiola in saying Chelsea should have the title wrapped up.
"They look at the moment in full confidence, powerful, strong. They don't concede goals. It's for them to lose it."
Second placed Tottenham are Chelsea's closest challengers and their 1-0 victory against Middlesbrough meant they are still nine points behind.
When Son Heung-Min was fouled by Bernardo in the 58th minute at White Hart Lane, Tottenham striker Harry Kane stepped up to convert the penalty for his 16th goal of the season.
It was a first win in three league games for Mauricio Pochettino's team, who are unbeaten in their last nine.
"When you don't kill the game you leave it open. In the last second you can concede, that's the Premier League. Thankfully it didn't and we're happy," Pochettino said.
At the KCOM Stadium, Liverpool fell behind in the 44th minute when Alfred N'Diaye took advantage of goalkeeper Simon Mignolet's poor handling to bag a debut goal.
Klopp's side were finished off in the 84th minute when on-loan Everton striker Oumar Niasse raced clear to boost third bottom Hull's survival bid.
"Obviously that was not good enough. We gave both goals away easily and the overall performance was not like it should be," Klopp said.
"It makes no sense for us to play like this. We need to wake up, that was not acceptable."
Liverpool have won only once in their last 10 games in all competitions and will be knocked out of the top four if Manchester City avoid defeat against Swansea on Sunday.
Sunderland stunned former boss Sam Allardyce with an first half goal rush to demolish fellow strugglers Crystal Palace 4-0 at Selhurst Park.
