Former Real Madrid GM Jorge Valdano admits he doesn't understand Jose Mourinho.

Valdano left Real after regularly clashing with the coach last year.

"As for Mourinho, he is a coach with a sensitivity opposite mine and that is reason enough to understand why we failed," said Valdano, who was quick to praise Barcelona coach Pep Guardiola.

"He's a true example of leadership applicable not only in the world of football. In short: an example. For someone similar I would say Marcelo Bielsa."
