I said
many teams. Like, all the different teams in pot 4 of the draw.
It doesn't take much thinking to say that Man City and Borussia Dortmund were the strongest teams in pot 3 of this season's draw. But how do you judge between Shakhtar Donetsk, Marseille and CSKA Moscow? Or between Ajax and Galatasaray? Or Napoli and Real Sociedad? You don't watch them often, they rarely play against each other, ,so all you have to go by is their league position (and of course the perceived strangth of the league they play in) and their performances in Europe.
If you want to build an argument to support your view, you are better off basing it on objective facts. Subjective criteria are easily fitted to
any opinion. In the extreme, you'll have people stating that Bayer Leverkusen have to be crap
because they were drawn in Man United's group, based on the "fact" that United always get easy groups. You are not in that category, but you do open a can of worms if you let a subjective assessment of the quality of a load of players you don't watch weekly be your main way of telling the strength of teams.
My point is: If you come up with concrete claims (e.g. "Their groups are usually super-easy"), you should also have something concrete to back them up with.
Based on my little research earlier today, I'm ready to
admit that United have had some quite easy groups over the last 15 years. Not that it has always looked easy when the games have been played
