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.
