So after going on a miserable run of nine games without a win across all competitions, Arsenal got back to winning ways with an impressive comeback win over West Ham on Monday night.

Freddie Ljungberg's side didn't do things the easy way in the clash, losing Hector Bellerin in the warm-ups, seeing Kieran Tierney go off in the first-half, and watching Angelo Ogbonna score a deflected header before the break. The Gunners however turned things around in the second-half, with goals from Gabriel Martinelli, Nicolas Pepe and Pierre-Emerick Aubameyang giving them all three points.

And in truth, it was the north London side's first two goal-scorers that made the result possible. The duo made a rare Premier League start (in Martinelli's case it was his first ever), and they both delivered emphatically on their manager's trust of them.

Ljungberg's first couple of games in charge saw him use Joe Willock as the number ten, and Alexandre Lacazette as the out-and-out centre-forward. That all meant Mesut Ozil and Aubameyang had to make do with playing from out wide - whilst the pair have had experience in that position previously, there is no doubting they had to sacrifice their more natural roles.

But against the Hammers, the Arsenal boss dropped both Willock and Lacazette to the bench, and brought in Pepe and Martinelli. Two natural wide-men playing in roles that they were comfortable with allowed Ozil and Aubameyang to also play in positions that are their strong suit. It really was a case of putting square pegs in square holes.

And with Pepe and Martinelli, the Gunners were given some much-needed width. For all of Ozil and Aubameyang's talents, they tended to drift inside to see more of the ball, which meant that the north London side became a lot more narrow and easier to stop. But in having two wingers hugging the touch-line and with the ability to beat opposition players one-on-one meant space for their other key stars opened up.

As per Sofascore, Pepe and Martinelli combined for 11 attempted dribbles, proving that the Gunners were keen to let the duo create havoc from out wide, rather than having them come in as inside forwards. The side had a lot more balance to it with the set-up, and it was no surprise to see them rack up ten total shots, and boss the possession stats too (65%). Ljungberg has been shown the way forward and he would do well to stick to it.

Meanwhile, Arsenal fans have been raving about this ace's masterclass against West Ham.
