Arsenal's 11-game winning run was finally ended as two Luka Milivojevic penalties earned Crystal Palace a much-needed point in a 2-2 draw at Selhurst Park
Manchester United eased the pressure on manager Jose Mourinho by seeing off Everton 2-1 at Old Trafford Sunday, as Chelsea leapfrogged Manchester City into second with a 4-0 thrashing of Burnley.
Arsenal's 11-game winning run was finally ended, though, as two Luka Milivojevic penalties earned Crystal Palace a much-needed point in a 2-2 draw at Selhurst Park.
Sunday's action on the field was overshadowed by the ongoing investigation into the helicopter crash Saturday evening that is feared to have killed Leicester City owner Vichai Srivaddhanaprabha.
A minute's reflection both in honour of Remembrance Sunday and the crash was held before kick-off at all three matches.
There was an even more poignant scene at Old Trafford as the 12 Thai boys rescued from an underground cave in July were in attendance and given a rousing reception by supporters.
United's fifth defeat of the season to Juventus in the Champions League Tuesday had put Mourinho's position in peril once more.
But he got the slice of luck he needed when Paul Pogba's penalty was saved by England No 1 Jordan Pickford, but rolled kindly back into the Frenchman's path to slot home the opener.
The United fans still weren't happy with Pogba, though, as he received jeers for his laboured run-up to the spot-kick.
Pogba made some amends as it was from his pass Anthony Martial curled home a fine second four minutes into the second half.
However, another sloppy pass from Pogba helped get Everton back in the game as Gylfi Sigurdsson scored from the penalty spot after Chris Smalling chopped down Richarlison.

Chelsea enjoyed a far more comfortable afternoon to close to within two points of Liverpool at the top of the table despite the absence of top scorer Eden Hazard with a back injury.
Alvaro Morata, Ross Barkley, Willian and Ruben Loftus-Cheek were all on target to ease concerns over who could carry the goalscoring burden without the Belgian for Maurizio Sarri's side.
The Italian remains unbeaten since taking charge at Stamford Bridge, and Sarri was also happy with a better defensive display than in recent weeks.
The Gunners' winning run had raised hope of an unexpected title challenge from Arsenal.
However, their defensive deficiencies were shown up in rash challenges by Shkodran Mustafi and Granit Xhaka to give Milivojevic the chance to earn Palace a share of the spoils.
In between the Serbian's spot-kicks, a brilliant Xhaka free-kick and Pierre-Emerick Aubameyang's controversial ninth goal of the season, after he pounced on a knockdown from Alexandre Lacazette's hand, had put Arsenal in front.
And Emery admitted his side still have plenty to learn if they are to compete with the Premier League elite.
