Arsenal got their season up and running by coasting to victory in their second-round Carabao Cup tie at West Brom - with Pierre-Emerick Aubameyang hitting a hat-trick on his return to the side.
With pressure building on manager Mikel Arteta already after two defeats at the start of the new Premier League campaign, there was welcome relief as the Gunners smashed their hosts 6-0.
Aubameyang had been struck down by Covid on the eve of the new season, missing the loss at Brentford and coming off the bench in defeat to Chelsea.
He will not have scored many easier goals than the first-half brace he grabbed here before adding a fine third for the match ball as Nicolas Pepe, Bukayo Saka and Alexandre Lacazette also found the back of the net.
Saka was lively and Martin Odegaard impressed on his second debut for the club following his permanent switch from Real Madrid last week - but Arteta and his side will not be judged on such tests as this.
