Pierre-Emerick Aubameyang and Mohamed Elneny struck for Arsenal as they put their Europa League disappointment behind them in a 2-0 win over Newcastle.
The Gunners lost the first leg of their semi-final against Villarreal in midweek and sought a confidence boosting victory in the Premier League.
It came to be, albeit it in fairly uninspiring circumstances.
A first half shot from Egyptian ace Elneny crept into the back of the net after Aubameyang scuffed an attempt on goal.
And a dreary game was given a second goal just after the hour-mark when Aubameyang sent the ball home from a lovely Gabriel Martinelli cross.
It was the fifth successive game in which he has scored against the Magpies, in his first start since returning from a bout of malaria.
There was some bad news for the Gunners, who move back ahead of Aston Villa into ninth, 12 points behind fourth-place Chelsea.
