Arsenal put behind their recent woes as they emphatically defeated Everton at Goodison Park.
Danny Welbeck opened the scoring on seven minutes, put through by Alexis Sanchez to round Joel Robles and slot home for his fourth of the season.
On 42 minutes, teenager Alex Iwobi marked his maiden Premier League start with a first goal for the club.
The results leaves the Gunners eight points behind leaders Leicester City.
It was a first win in four league matches for third-placed Arsenal, who dominated the game.
In contrast, Everton failed to test Arsenal properly and had just two shots on target as their dreadful home form – now four defeats in five in the league – continued.
Arsenal began the week being knocked out of the FA Cup, losing 2-1 to Watford in the quarter-finals.
Then on Wednesday they lost 3-1 to Barcelona at the Nou Camp, as they were dumped out of the Champions League.
With only the league to focus on now, this was a must-win match for the Gunners if they were to have any chance of staying in touch with Leicester.
And with fifth-placed West Ham only three points behind before kick-off, Arsenal are also anxious to hold onto their Champions League place.
In the event, they responded to last week’s disappointments with a positive performance and earned a first league win since they beat Leicester 2-1 on 14 February.
