I've never got on the anti-Mourinho bandwagon, mostly just because his record speaks for itself, but if he can't win against this clueless blob, then his reputation is in tatters as far as I'm concerned.
Mourinho’s standing (amongst players importantly) has never really recovered from the Physio incident. Players were definitely turned off against him since then. His methods maybe not translating to the modern day footballer either.
Actually think the documentary has done him no harm as far as the media who had also sticking with the narrative of him being dour and miserable in his later years.
