Mourinho is unhappy with his players paying compliments to their great rivals, Barcelona.
Higuain broke the code when discussing his Argentina teammate: "It's a pleasure to play alongside Messi. We understand eachother well."
But Mourinho is unlikely to take any action as even his spokesman, Eladio Paramés, tweeted in recent days: "Barcelona is currently the best team in the world. To say otherwise would be lying."
