Arsenal increased their lead at the top of the Premier League table to eight points with a dominant victory over managerless Crystal Palace.
The Gunners were clinical in the final third, with Gabriel Martinelli firing them in front before Bukayo Saka found space in the box to stroke in a second before half-time. Palace hit the post through Wilfried Zaha and threatened on the break, but their miserable run continued, with the decision to sack Patrick Vieira not paying immediate dividends.
Granit Xhaka made it 3-0 with a scruffy finish from Leandro Trossard's incisive through ball to put Arsenal in complete control. Palace midfielder Jeffrey Schlupp did at least score their first Premier League goal for a month by smashing in a loose ball from a corner, but Saka lashed in Kieran Tierney's cutback to make it 4-1 soon after.
