Mourinho explained why he had a black eye during an interview with Spanish channel La Sexta's El Chiringuito.
Host Josep Pedrerol also jokingly brought up the previous conflict between Valverde and Tchouaméni.
Mourinho said: "No, it's not like that. It was poor Lacosta, a Castilla kid, whose kick hit me. I was wearing glasses at the time, and the ball hit me directly."
Mourinho then humorously added: "But he wasn't called up for the last game because of it."
Mourinho also spoke about the Real Madrid locker room he saw after taking over.
"What I saw was a locker room very eager to win. What I saw was a locker room willing to listen to common sense, because from day one, all my requests to them were common sense."
"So far, I haven't encountered any situations that required me to be that tough leader. I can indeed be that person sometimes, but they allowed me not to show that side."
Mourinho also revealed the team's current discipline and daily requirements.
"Their performance is impeccable. I told them that what I ask for is common sense."
"For example, I ask them to arrive at the training ground an hour early, not 5 minutes early; that's common sense. This is today's football. You must arrive early, have a proper breakfast under the supervision of a nutritionist, go to the gym for preventive training every day..."
"All of this is for yourselves, and also for our entire team. All my requests to them are just common sense."
