Arsenal will face European side rival West Ham in midweek, so let's see how they will line up.

In Last Saturday's win over Southampton, Arteta lined up the same line-up, but the performance was greatly improved compared to the game against Everton.
Critics may blame the Saints' defence for a lack of personnel, which hastily signed goalkeeper Caballero and multiple suspensions or injuries on the defensive line.
Arsenal's task is to come up with a similar performance against West Ham on Wednesday, and Arteta is likely to follow a similar line-up. Let's predict the lineup.
goalkeeper
Another clean sheet and top-notch performance proved that Amsdahl would continue to sit firmly in the starting position.
Leno still hasn't been able to return to the matchday squad, so there are few chances to start. If he continues to be absent, Arthur Okonkovo will sit on the bench.
Defense
Even though Tavares is in good shape, Tierney has contributed two assists since his return. He will likely continue to start.
Several other people on the defensive line should be well predicted. Arteta has confirmed that Gabriel was not injured against the Saints and only went off because of a yellow card, so he will start with Ben White and Fuan Kenyo.
midfielder
Xhaka and Thomas performed better against the Saints than they did against Everton. Arteta hopes they can form a tacit partnership. In such a key game, the two are expected to start.
In front of the two, Erdegaard, who has scored three goals in the last three games, is difficult to ignore. With Smith Rowe injured, his starting odds are high.
striker
The combination of forwards will depend on the situation of Aubameyang, who missed the last round of matches for violating discipline.
Considering that the behavior is not serious, he may not be absent for too long. But after ending the goal drought against the Saints, Lacazette could win the starting spot.
On the flanks, Martinelli and Saka should continue to start. It is possible that Smith Rowe will regain the position on the left from Martinelli, but with the latter performing well, Arteta may not be in a hurry to get him back.
Arsenal predict the starting line-up
Will Pierre-Emerick Aubameyang return against West Ham?
The big news ahead of Arsenal's game against Southampton was that Aubameyang would miss the game.
Charles Watts was the first to reveal Aubameyang's absence from training last Friday and the possibility that he might miss Saturday's game.
Arteta then confirmed that he was not included in the squad for disciplinary reasons.
David Ornstein revealed more details, reporting that Aubameyang and the club had agreed on a private outing, but returned too late to break the rules.
This has had a negative impact on the current epidemic prevention regulations, leading to disciplinary action last Saturday.
Although the rhetoric was tight in the post-match interview, Arteta gave the time of the shooter's absence.
Asked if the captain would return against West Ham, Arteta replied in the affirmative.
This is the most information journalists get from the mouth of the tarsant, but it implies that the punishment of Oba will not be long-term.
Fortunately, Arsenal scored three goals against Southampton and scored an easy victory without feeling the impact of Aubameyang's absence.
