No doubt, the odds seems to favour Arsenal tonight, but I wouldn't want to write Manchester united off either. Arsenal will be without a very important player like Gabriel after having a knock in their last game against West Ham, which I'm not sure of how the team will play tonight without him. Aside that, I think Arsenal have other areas covered with qualities. Martinelli use to perform well against Manchester united, but I'm not sure of what he will bring to the table tonight, considering the fact that he hasn't being his best. For united, Bruno has been very good lately, so I will just want to enjoy a master class from both him and Odegaard tonight. The better side will definitely win the game. Good luck to both teams.
