Sancho was also world class at Dortmund. Lot's of players are world class at Dortmund only to flop somewhere else, but point taken.
Still gotta love how a 30 goal a season wide forward in Rashford isn't world class, and yet a brand new kid on the block who has yet to show anything similar in Saka is somehow closer to being WC
Also the bolded part I agree with, but imagine that at this moment in time saying Bellingham is anywhere near those guys. If anything he is still a level below Pogba. At this age Pogba was having WC performances and led Juve to the CL final which prompted us to outspend Real and buy him. Let's wait and see if Jude can get close to that.
I will say this though: unlike Pogba, Bellingham made the right choice in signing for Madrid. Unlike here or say Chelsea, Real will never let him turn into a slacker or placate his every whim the way we did with Pogba.
