Bayern Munich chairman Karl-Heinz Rummenigge has demanded Franck Ribery end his tirade against Manchester City boss Pep Guardiola.
Ribery twice last week attacked his former Bayern coach for the way he was treated last season.
But Rummenigge said: "There is no reason for negativity against Pep Guardiola. We have gained a lot with him, benefited from him.
"Negativity does not work."
Guardiola was asked about Ribery's criticism yesterday.
"I have something to say about Ribery: I love him very much," he replied with a smile.
