Every manager working at the top end of Europe's top leagues is a strong personality.
To a point. And some will use it to get performances out of their players, ie. Mourinho, SBR, SAF, etc. And others will alienate them ie. AVB, O'Neil, Souness, Dalglish, etc.
Mourinho's players love him just as much as SBRs. The man is doing something right.
Real Madrid's players absolutely hated his guts didn't they?
