Arsenal have lost 3-0 to Manchester City on a miserable night for Mikel Arteta's Gunners at the Etiahd on Wednesday.
David Luiz was sent off as Pep Guardiola's men eased to a comfortable triumph behind closed doors as the Premier League returned after 100 days absence.
Luiz, who came on as a first-half substitute, failed to clear his lines before Raheem Sterling slotted home in City's opener moments before the break.
The former Chelsea defender saw red after pulling back Riyad Mahrez after the interval to give away a spot kick, which saw Kevin de Bruyne sending Bernd Leno the wrong way for City's second.
The highly-rated Phil Foden, who entered the fray late on, grabbed a third after pouncing on a rebound from Sergio Aguero's shot which hit the post.
After a bright start Arsenal were disappoinitng as manager Mikel Arteta left Alexandre Lacazette on the bench while Mesut Ozil didn't even make the 20-man travelling squad.
Pierre-Emerick Aubameyang and Eddie Nketiah looked lively on occasion but it was City who were more dominant force.
De Bruyne, Sterling and David Silva were all denied by Arsenal keeper Bernd Leno, who was the visitors best player.
Three points for Guardiola's side means league leaders Liverpool are six points from winning the Premier League - meaning no title bid in Sunday's Merseyside derby.
Both clubs showed their support for the Black Lives Matter movement for racial equality when all players took a knee and the words 'Black Lives Matter' replaced players' names on the back of their shirts.
