There was a reduced crowd at Stamford Bridge for the first time since restrictions placed on the club prevented them from selling tickets not purchased prior to UK government sanctions imposed on owner Roman Abramovich.
However, Arsenal were able to sell out the full away allocation and the visiting fans were jubilant when Nketiah took advantage of more shoddy Chelsea defending from Malang Sarr to put his side ahead for a third time. Bukayo Saka then sealed the win with a stoppage-time penalty after he had been brought down by Azpilicueta.
At the bottom of the table, Everton snatched a much-needed point in their battle to beat the drop as Richarlison’s 92nd-minute strike earned a 1-1 draw against Leicester at Goodison Park.
The Foxes led for 87 minutes after Harvey Barnes’ early opener. Everton edge four points clear of the relegation zone, but Burnley can cut that gap when they host Southampton on Thursday.
Newcastle were also fretting about relegation at the turn of the year, but the Magpies are up to 11th after a sixth consecutive home win. Miguel Almiron scored the only goal at St. James’ Park to round off a disappointing week for Crystal Palace after their FA Cup semi-final exit to Chelsea.
