Goodbye Pep Guardiola

At the end of this April, Pep Guardiola has said officially leaving FC Barcelona. Pep Guardiola is one of the best coaches in the world. Leave Barcelona winning many titles.
I am very sorry to leave as a coach. It was the best, a great person and also a philosopher of football. always took things in philosophy.
People are very discouraged. Do not understand why Guardiola wants to leave. There are rumors that Guardiola has asked Sandro Rosell(chair) more power but had refused him. Guardiola apparently does not like some members of staff.
