It will be very detrimental when Martin Ødegaard has to undergo treatment due to injury and his absence will leave a void even though Arsenal can use other players as a replacement.
Arsenal will have a little problem after Martin Ødegaard was injured and his leadership on the field is very important because he is the team captain.
Arsenal also lost Mikel Merino who had a shoulder injury and Declan Rice because he was given a red card, Arteta will definitely be confused with conditions like this because losing important players can have a negative effect on Arsenal.
We hope that the injuries suffered by some players are not too serious so that they can return to strengthen the team after the healing is complete.
It is undeniable that Martin Ødegaard is a player who is quite influential in Arsenal's midfield so of course with the absence of Martin Ødegaard will make Arsenal's team performance a little different even though Arteta still has many other options to fill the gap. Martin Ødegaard has an ankle injury which is predicted to not take long to recover from this injury so I think if that is the case there will be no major impact on the team as long as their influential player does not suffer a long-term injury.
Arsenal will not play optimally if one of their key players is injured, Odegaard plays an important role for Arsenal, so far he has performed well in organizing attacks, it is very unfortunate that obstacles like this occur when Arsenal will play their first North London derby this season. For now, Arteta's team must work harder in every match until their key players return to the field. And hopefully Odegaard and Merino recover quickly.
