A sine wave is a mathematical curve that describes a smooth periodic oscillation. This wave form is used in mathematics and applied sciences, but Arsenal’s current situation can be likened to a Sin Ø curve.

After losing 2-0 at the Emirates to a Lukaku-boosted Chelsea in the Premier League, Arsenal whitewashed West Bromwich Albion 6-0 at the Hawthorns to book a place in the Round 3 of the Carabao One cup. It was the first time Arsenal scored 5+ goals under Mikel Arteta.

@OptaJoe: 6-0 – Arsenal’s 6-0 victory over West Bromwich Albion at the Hawthorns last night was their biggest away win in any competition since a 6-0 win over QPR in the FA Cup in January 2001 under Arsène Wenger. Resurgent.

With the bitter taste of back to back opening defeats without scoring – a record in the history of the club – Arteta needed a win and it came easy at the hand of the Championship table toppers who fielded as much as 6 debutants in the game.

Aaron Ramsdale kept a clean sheet in his debut for the Gunners, Ødegaard made his second debut and Nuno Tavares his full debut. Aubameyang led the team and capped his 150th appearance for Arsenal with a hat-trick. Pepe had a goal and struck the woodwork twice. Saka was slick and capped his display with a goal, beautifully assisted by Ødegaard.

Kolasinac deputized as centre back with Holding, while Niles, El Neny also featured.

The 2-0 defeats to London clubs – Brentford and Chelsea was damning to the confidence of the fans and the team. Arteta blamed it on Covid-19 and the absence of key players in the team. The Gunners were without Aubameyang and Lacazette in the opening game of the season.

The club captain came on late against Chelsea, showed some flashes of greatness and capped up his return with three goals last night. He wasn’t shanked off to work the flanks. He poached on two goals and added a beautiful third. Will Arteta play him in same position against City?

Few days ago, there were questions on if Arsenal will score or win a match this month. Today they are boosted by a 6-0 win in preparation of playing Man City at the weekend. Yes, it was only the league cup and West Brom but Arsenal needed the win to push them up the sin curve on every level – hopefully not to drop on that curve.

Oh, Arsenal will play Wimbledon in the third round. That should be another high scoring encounter.
