It's simple, Mourinho is a sore loser.
He instills this mentality into his players in a bid to make them competitive. That's how Chelsea were in CL final 2008 - remember the Drogba red card situation? Same applied at the "scandal of Stamford bridge" and the "scandal of the bernabeu", both games against Barcelona where Mourinho sides were totally out played.
It's said that it's good to be a bad loser because that means you never want to lose and hate the idea of it.
A sore loser is a different thing altogether and it damages the game. One thing is for sure, I could not see myself supporting a side with Mourinho, Pepe or Ramos on the books.
