Arsenal's first two games to start the 2021/22 season couldn't have gone much worse.
The Gunners opened up the campaign with a morale crushing 2-0 defeat to Brentford, before losing by the same score-line to Chelsea.
After two poor performances from his side, Mikel Arteta fielded a strong XI for their Carabao Cup second round clash against West Brom.
And Arsenal showed their dominance as they ran riot at The Hawthorns.
Pierre-Emerick Aubameyang (2) and Nicolas Pepe both found the net as Arsenal led 3-0 at the break.
Bukayo Saka made it 4-0 just after half-time and it came after some lovely build-up play.
The English winger drove forward, played a sumptuous one-two with Martin Odegaard, before expertly finishing past the onrushing Alex Palmer.
What a lovely assist that is from Odegaard.
That touch of brilliance shows exactly why Arsenal were so desperate to re-sign him from Real Madrid this summer.
Odegaard was not on the pitch much longer as he made way for Ainsley Maitland-Niles.

But the goals kept coming after the 22-year-old departed.
Aubameyang got his hat-trick in the 62nd minute with a lovely curling finishing, before Alexandre Lacazette made it 6-0 just a few minutes after coming on.
Lacazette's goal proved to be the last on what was a very satisfying evening for The Gunners.
After a poor start to the season, Arsenal needed a convincing win against the Championshio outfit and that's exactly what they got.
They will be hoping to get their first Premier League points of the season on the weekend when they take on Manchester City at the Etihad Stadium.
