Thats literally drawing parallels for the sake of drawing parallels. I could say us and NOTTINGHAM Forest are similar, both have European titles, both havent won anything notable for a while, doesnt make us in any way similar as clubs though does it?
United exploited their commercial potential heavily whilst we stagnated and they're still reaping the benefits of that to this day. The only parallel that exists is we're both rivals. They are far better resourced than we are and regularly make big name signings, honestly its not even close.
If there is going to be a parallel drawn it certainly wont be at this moment in time, more likely way in to the future. Also you cant just say the squad quality is irrelevant, that makes your attempted point far too arbitrary.
