Pedro turned out terribly for Pep didn’t he? Moreover, it is disingenuous to compare any player to Ronaldo or Messi. As a direct comparison Ronaldo has the best work ethic in football. Far above anything Sane will ever achieve. I get the comparison you tried to make was that Sane is better than Torres, but you could have tried to make a different analogy.I saw it and wasn't impressed.
You don't replace "potential" Ronaldo with "potential" Pedro.
