Arsenal eased fears of being dragged into a relegation battle with a stunning 3-1 win over Chelsea on Saturday.
Mikel Arteta led Arsenal to win the FA Cup the last time they faced Chelsea in August, but less than five months on the Spaniard was under intense pressure after a run of one win in 10 league games.
Arteta had bemoaned his side’s fortune in recent weeks, but the Gunners’ luck turned on a night when he gave youngsters Gabriel Martinelli and Emile Smith Rowe the chance to shine in the absence of more experienced figures such as David Luiz, Willian and Pierre-Emerick Aubameyang.
Kieran Tierney won a soft penalty for a push by Reece James and Alexandre Lacazette slotted home the spot-kick to open the scoring on 34 minutes.
Granit Xhaka then answered his critics after being stupidly sent off in a 1-0 defeat to Burnley earlier this month with a brilliant free-kick to double Arsenal’s lead just before half-time.
A third consecutive away defeat for Chelsea further damages their chances of competing for the title and there was no way back for Frank Lampard’s men once Bukayo Saka chipped in off the inside of the post 11 minutes after the break.
Tammy Abraham did pull a goal back five minutes from time and Chelsea could have set up a grandstand finish in stoppage time, but Jorginho’s penalty was saved by Bernd Leno.
Victory lifts Arsenal up to 14th, six points clear of the relegation zone, while Chelsea drop down to sixth on goal difference.
