Mourinho was asked about Ramos' behaviour in wearing Mesut Ozil's shirt under his own after the German had been taken off at halftime of their win over Deportivo La Coruna.
"You'll have to ask him (Ramos)," replied Mourinho. "Ask him why he did it. Not me."
Mourinho did hint he expected better from Ozil.
Asked why the German hadn't played much this season, he added: "Less playing time or less quality playing time? Because, the better the quality, the more playing time."
