Arsenal
Arsenal need to improve their attack, and make sure to score as many goals as the opportunities as they create. If Arsenal gets a good striker in the transfer chance and get reinforcements in some other positions in the team, their chances of doing very well in the champions league round of 16 more than they did in the group stages will be higher. I see Roma coming to the champions league next season, I see Mourinho as someone with a plan, they look to be on that track already to achieve that with their current position on the table.
Exactly. Arsenal needs to improve its attack. Seriously, it's getting weaker, and as you said, they need to use every single opportunity that will come their way to score a goal. Currently, I think that is the position that Arsenal needs to strengthen more in their squad. Although other squads also need some reinforcements, I think the main weak position in the squad is the attacking position. The attacking position doesn’t get as strong as it is, but I think the round 16 matches will be tough, so I hope before then they will try and get someone to strengthen the attacking position so that they will do more than they did before.
