Cristiano Ronaldo said that he would not discuss "the crisis of others" when questioned on Real Madrid's recent problems during a press conference on Monday afternoon.

Ronaldo left Madrid for Juventus in the summer, and the famous number seven is currently preparing for Tuesday's Champions League clash against another of his former employers, Manchester United.

While Juventus have won 10 of their 11 matches at the start of the 2018-19 campaign, Madrid have lost four of their last five in all competitions and are without a victory since September 22.

Ronaldo scored 450 goals in his nine seasons at the Bernabeu, helping the capital giants win two La Liga titles, two Copa del Rey crowns and four Champions Leagues.

However, the 33-year-old has seemingly moved on from thinking about the Spanish outfit as he prepares for Tuesday's clash at Old Trafford.

"It's all right. You cannot cry. I do not have to talk about other clubs. Everyone knows the story I had at Real Madrid and what is important, tomorrow's game. It's not for me to talk about the crisis of others," Ronaldo told reporters.

Ronaldo, who helped United win three Premier League titles and the Champions League during his time in England, has scored five times in 10 appearances for Juventus this season.
