Chelsea manager says he knows why Bayern Munich manager is bald

Chelsea manager Jose Mourinho says he knows why Bayern Munich manager Pep Guardiola is bald.

"When you enjoy what you do, you don’t lose your hair, and Guardiola is bald," Mourinho said, according to El Confidencial(translated by The Telegraph). "He doesn’t enjoy football."

That's one explanation. Another could be that Guardiola is a 43-year-old man in a highly stressful line of work. But that doesn't leave much room for smack talk.

According to The Telegraph, this little feud started with a discussion about the optimal length of grass on a soccer pitch. Some people can be set off by just about anything.
