Real Madrid coach Jose Mourinho says he won’t make any comment on forward Cristiano Ronaldo’s surprise declaration that he’s unhappy at the club. “I am not going to say anything about that”, the Portuguese coach said when asked about his compatriot and star striker’s troubles during an interview with sports daily AS published Thursday. “I am ready to talk about everything. I have answered in depth and sincerely. But don’t ask me about Cristiano. You have to understand. Please don’t insist,” Mourinho said. The 27-year-old Ronaldo confessed to being “sad” when asked why he had not celebrated either of two goals he scored in Real Madrid’s 3-0 win over Granada on Sunday. Ronaldo has still not explained why he is unhappy, saying only on Sunday that it was professional, not personal. “People know why,” he was quoted as saying. The striker took to his Facebook page and Twitter on Tuesday to deny financial motives for his misery.
