I think Arsenal's match against Brentford perfectly showcased how a team can overcome lineup issues and still secure a result. Missing key players like Havertz, Saka, and Rice, the Gunners started with strong pressure but conceded first due to Odegaard's mistake in midfield. Mbeumo, who shone in Brentford's attack, later made a crucial error, allowing Jesus to equalize with a rebound.
In the second half, Arsenal looked much sharper. Set pieces made the difference, with goals from a corner and effective pressing turning the tide. Merino and Nwaneri deserve special mention, while Partey was a rock in midfield. The 3-1 win was a solid return to second place in the table, but without Raya's heroic save in the first half, things could have gone very differently.
Brentford have a bad defense, although Arsenal have scored 3 match, but all the goals are from corners and it's more like due to their luckiness. If Arsenal were match against top 5 teams, they might not score a goal or just one because the defenders are top class.
I think Arsenal already have a solid squad, even though there are many players injured, but they still have enough players which I think they don't need to recruit new players.
