The jet-setting of both players during the winter break has infuriated Mourinho, says Sport, who spoke openly about how disappointed he was to see some of his players being snapped at glamour spots around the world over Christmas and the New Year.
The relationship with Kaka is now said to be at its lowest ebb, with the player actively seeking another club where he can enjoy greater playing chances. Nuri Sahin's emergence and Mesut Ozil's form has made Kaka surplus to requirements as far as Mourinho is concerned.
Meanwhile, the coach's relationship with Ronaldo is also becoming increasingly frosty. Mou failed to defend Ronaldo after the El Clasico jeers from Real fans and even their agent, Jorge Mendes, appears powerless to prevent a major blow-up.
It's claimed all hell will break loose between the Portuguese should Real fail to finish with a major trophy this season.
