Gustavo has been linked with a move away from Bayern Munich, following Javi Martinez’s arrival at the Allianz Arena.
“Luiz Gustavo will stay on, this is a fact,” Sammer told Sport BILD.
Gustavo said: “I feel great being a Bayern Munich player. I absolutely enjoy it.
“I really did not think about leaving the club at any second.”
Gustavo has just under three years left on his current contract with Bayern Munich.
