I’ve watched between 15-20 full Dortmund matches this season (Sancho). Two seasons ago, I watched 15-20 Dortmund matches (Dembele).
Dembele is all about speed. He would make decisions that would leave you scratching your head. But the speed was electric.
Sancho IMHO, is much more polished. Not as much pace, but able to unlock defenses through clever runs, passes and movement. He is much more mature as a player than Dembele was. Control, technique, 1v1 ability better than Dembele at the same age.
Dembele will likely be sold this summer. Would you rather have Dembele or Sancho? Sancho for me, not close.... and I think that’s why he will cost 120m+
