Bayern Munich president Karl-Heinze Rummenigge won't hear criticism of Pep Guardiola.
Guardiola left Bayern as champions last summer to take charge of Manchester City.
Rummenigge declared: "I would say that Bayern has never played as well as when Pep was the coach.
"We have always been successful, but rarely were we also so beautiful.
"Under the command of Pep, suddenly all of us could enjoy a good team."
