Chelsea boss Jose Mourinho has mocked Bayern Munich rival Pep Guardiola.
The former Real Madrid coach never saw eye-to-eye with Guardiola while he was in charge of Barcelona.
Mourinho told Gazzetta dello Sport: "If you really love what you do, you don't lose your hair. Look at Pep. He's going bald. That's because he doesn't like football."
Mourinho also had a potshot at current Real coach Rafa Benítez during his time at Inter Milan: " He destroyed the best team in Europe in six months", and even Carlo Ancelotti: "In the history of the Champions League there is only one club and one coach who let a 3-0 lead slip in the final and ended up losing."
