When Gabriel Jesus got injured, Arteta has floated the possibility of using Gabriel Martinelli through the middle and wants to add attacking reinforcements. But Eddie Nketiah is ready to fill the hole in Arsenal's attack, we saw Nketiah doing the job and against Westham United, he proved himself. I dont know how far Arsenal will go with this but there are also reports that theyre trying to add another forward to compliment the attack in the absence of Gabriel Jesus. Theyre a lot of games to be played, so I expect reinforcement.
They can't get someone right now, can they? It's not the transfer window right now as far as I know and not for a while longer. After that, depending on how Gabriel Jesus feels then maybe they could get another player.
How long will he be out? Last I know was like 3 months for the injury and it has been nearly a month already since that was said, which means only 2 months left. If that timing is correct then they shouldn't really get someone for only 2 months absent. If they could hold off for 2 months that would be better. However, if they are looking to get someone for long term, like even if Jesus was healthy type of deal, then it would be reasonable for sure.
As far as I know, I think he will be out for at least two more months which could be until February 2023. It would be safe to say that he will at least miss around 8 to 10 matches as a result of the injury, which is very unfortunate for both Arsenal and their fans.
In my opinion, the coach did a good job by playing Eddie Nketiah against Westham United. But I do not think that this is a foolproof plan for the next few months. It seems to me that Gabriel Martinelli would be a better option. However, I believe the coach would need to do some trial and error in order to find out what works best for him.
