Arsenal moved on from their surprise midweek defeat to Swansea in style as they beat Everton 5-1 with Pierre-Emerick Aubameyang scoring on his debut.
Aaron Ramsey fired Arsene Wenger’s side ahead on six minutes, after being set-up by Henrikh Mkhitaryan, before Laurent Koscielny doubled the hosts’ advantage after 14 minutes with a back-post header.
Ramsey then added his second goal and Arsenal’s third on 19 minutes, lashing home from the edge of the box following a pass from Alex Iwobi.
And club-record signing Aubameyang added a fourth eight minutes before half-time when he was adjudged to be onside.
Shortly after the hour mark substitute, Dominic Calvert-Lewin reduced the deficit with a header, his eighth goal of the season, but Ramsey completed his hat-trick on 73 minutes to round off the win.
Mkhitaryan, on his home debut, set up three goals – two of those for his ex-Borussia Dortmund mate.
The victory takes the Gunners to 45 points, three behind Tottenham Hotspur.
