Real were stunned 1-0 last night.
Mou said: "I do think it has anything to do with it. I think today's match was no different from those against of Getafe and Granada which we won.
"So I don’t think that the rumours of the last couple of weeks have anything to do with it. It is about a state of mind and of two or three who aren’t thinking like the rest. They are the minds of players which are not committed and for whom football is not a priority in their lives. There aren’t many involved and it's complicated, but I’m coach and if there are those less committed then it is my fault."
