By their standards presently, every club that's normally an average team is big for them and true like you said , they could have been punished had they played against a side like Liverpool. Observed that no striker scored for Man UTD yesterday? Meanwhile they had a striker in the game. Since this season started, Rasmus Hojlund just has two goals and he was a big money spending when he was brought into the club last season from Atalanta.
Even his replacement, Joshua Zirkzee is nothing to write home about because the both just play like a bunch of confused individuals.
I agree with what you said. Man United does not have a clinical striker, and this has been going on for almost 2 seasons. It's a shame that Ten Hag made a scene in the past, and because of that, Ronaldo chose to leave Man United. If that doesn't happen, I think Ronaldo can probably still make a contribution that Man United's current strikers can't (Hojlund and Zirkzee).
Besides that, there is a question that really bothers me. Why wouldn't Amorim sell Hojlund and Zirkzee and use his money to sign Osimhen? If Osimhen is too expensive, at least Amorim could still sign Gyokeres as an alternative.
