Aston Villa closed to within four points of the Premier League summit with an impressive 2-0 win at Newcastle, while Chelsea climbed into the top four on Sunday.
Leaders Arsenal can stretch their advantage over Villa and Manchester City back to seven points when they host Manchester United later.
But Villa bounced back from a shock 1-0 defeat at home to Everton last weekend to remain on the fringes of the title race. Emi Buendia put Unai Emery’s men on course for their first win at St. James’ Park since 2005 with a brilliant strike from outside the box on 19 minutes.
Newcastle were shorn of inspiration without injured captain Bruno Guimaraes in a damaging defeat for their chances of Champions League qualification.
Ollie Watkins set the seal on Villa’s victory when the England international headed in Lucas Digne’s cross two minutes from time.
Newcastle slip to ninth but still only three points outside the top five, which will likely be enough for a place in the Champions League.
Even if Villa fall short on a first league title since 1981, they are well on course for a return to Europe’s elite competition with an 11-point advantage over sixth-placed Manchester United. Chelsea piled more pain on Crystal Palace with a 3-1 win at Selhurst Park.
Oliver Glasner promised to do his best to turn around a miserable run for the Eagles despite announcing he will leave the club when his contract expires at the end of the season.
The Austrian was furious at the manner club captain Marc Guehi was allowed to depart for Manchester City earlier this week and could also lose star striker Jean-Philippe Mateta before the transfer window closes.
Mateta wasted Palace’s best chance of a bright opening when he fired straight at Robert Sanchez.
But the home side never recovered after a wayward backpass from Jaydee Canvot freed Estevao to sprint clear and fire in Chelsea’s opener on 34 minutes.
The Brazilian then set up compatriot Joao Pedro to gallop in behind the Palace defense and double the Blues’ advantage just after half-time.
Enzo Fernandez’s penalty rounded off a fourth win in five games for Liam Rosenior since he took charge at Stamford Bridge.
Palace’s misery was compounded when England international Adam Wharton was sent off for two bookable offenses. After 11 games without a win, the Eagles are now looking over their shoulder, just eight points above the relegation zone. Nottingham Forest gave their survival chances a huge boost by inflicting just a second home defeat of the season on Brentford.
West Ham’s victory over Sunderland on Saturday piled the pressure on Sean Dyche’s men.
But they responded to move five points clear of the drop zone with a 2-0 win in west London thanks to goals from Igor Jesus and Taiwo Awoniyi.
