Arsenal captain Pierre-Emerick Aubameyang returned to goalscoring form as he was twice on target against a Norwich City side almost certain for Premier League relegation.
The Gunners seem to have got back on track following a slow restart and ran out 4-0 winners in their first competitive game at the Emirates Stadium in almost four months.
Aubameyang had not scored in his last four league games, his worst barren spell for over five years, but his opener against Norwich took him to 50 Premier League goals – the fastest Arsenal player to reach that milestone.
Norwich keeper Tim Krul was to blame, dawdling in possession and striking his clearance straight at Aubameyang, who simply tucked home into an empty net.
Four minutes later and the game was taken away from Norwich, Kieran Tierney and Aubameyang combining before the Gabon international fed Granit Xhaka, who hit his first Premier League goal in over a year.
In the second half, the Norwich bench were left incensed as referee Peter Bankes and VAR decided that Sead Kolasinac had not fouled Todd Cantwell inside the box.
Farke’s men had looked sharper for most of the second half, until their defensive frailties were once again laid bare for all to see.
A Norwich throw-in inside their own half was sent towards substitute Josip Drmic, who gifted the ball straight to the unforgiving Aubameyang – the striker more than happy to oblige in gobbling up the mistake for his second of the night.
The gloss was applied to this Arsenal display by debutant Cedric Soares, who needed just four minutes to mark his long-awaited bow with a goal as he struck sweetly from the edge of the box.
