That’s because they’ve played for other teams to be good for them. Sancho might of done very well at Salzburg and Molde. He jumped into a club that was a mess and has no structure… it’s very hard for any player to thrive for us at the minute…. We’ve got no clear plan or style of play like them teams you’ve just mentioned. We’ve gone from Ole to ETH so 2 different complete managers who see football differently, that wouldn’t have helped him either.Well you'll obviously get more chances if there's less competition.
I wouldn't say any of those players shone at international level either. They've just played a fair bit.
This started with a comparison to Haaland and Bellingham, with the clear implication being that they all looked good at Dortmund. The obvious difference is that Bellingham has looked good for Birmingham, England and Real Madrid, and Haaland has looked good for Molde, Norway, Salzburg and City, in addition to looking good at Dortmund.
Sancho has looked good for Dortmund.
