This is absolutely nonsensical.
You can't pick your opposition in knock-out football.
It's like when Utd fans vainly try denigrate L'pool's first 4 European Cups with lines like 'you had it easy playing Zurich the semi.' Conveniently forgetting it was straight knock-out European footie from the get-go back then when one mistake and you were out. Which happened three out of 4 seasons the early '80's to such 'stellar' outfits as Dinamo Tiblisi the first round and, in successive season's the third round, CSKA Sofia and Poland's Widzew Lodz. Liverpool, by far and away the best team in Europe back then, getting beat by far inferior sides on every level. Was the European Cup insignificant those season's too?
Regardless of the standard of opposition, or disparity in financial clout, Utd battled through 15 games to win the Europa League last year. Including 9 straight do-or-die knock-out European ties. Do I think they'd of had a different story if they'd of had the run L'pool had the knock-outs the year before? (Utd themselves, a CL calibre Dortmund side, a very good Villareal side consistently up the top of La Liga. And Sevilla going for a third straight win the final?). No question. But it's COMPLETELY immaterial as they got dealt the hand they got dealt and beat what was in front of them. It doesn't somehow lessen their achievement because they had an easier run FFS.
