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.
It's not a bad idea but I think with the current squad Arsenal can still be relied on Arsenal finished as group winners in the last round. Arsenal's next opponent is Porto, I don't underestimate Porto but I think Arsenal deserves to go through to the next round, I can't predict how Arsenal will play in the first leg, but in the second leg I can already imagine it Arsenal will destroy any team . The question is after Porto, who will be Arsenal next opponent? I hope not Real Madrid or Bayern Munich because this is the real opponent.
