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.
The position of being the favorite team or not will certainly greatly influence who Arsenal will face next if they succeed in eliminating Porto in the round of 16.
My prediction is that looking at the existing teams, there is a very big chance that Arsenal will meet one of these strong teams, and if that happens it will be very difficult for Arsenal to advance to the next round, but before that, they have to be able to overcome the Porto team which is quite good even though many people predict that Arsenal will beat Porto, but in my opinion, the chances of both teams are the same, because Arsenal can sometimes appear disappointing, such as when they lost to West Ham in the English Premier League.
