Dont even try and give Mourinho credit for Balo, that was Mancini.
it debatable that mourinho didnt develop him enough those are peak years to be taught habits. its not event that he doesnt develop youth. he has no care to. i dont think he knows the techincal side of the game enought to know how to teach little things like how to position yourself in space off the ball. but imagine balo being coddled by pep .
edit: balo with pep from the jump is ronaldo with ferguson. ronaldo under the wrong manager at a young age could see a different outcome
