Real Madrid coach Jose Mourinho refused to talk about the 15 points gap with Barcelona after their draw at Osasuna.

Mourinho feels there were problems from the first day of the season.

"The explanation begins on the first match day and since then things have happened that I do not want to talk about. After that, when the gap is big, one team plays without pressure and the other one feels like that they can't close the gap and there are motivational issues."
