After defeat at White Hart Lane, Koeman called for Saints fans to behave better.
"Yes, okay that is the reaction of the fans and I don't agree with that," the Dutchman said.
"I think everybody needs respect and normally the respect is high in the Premier League.
"I respect Mauricio very much and he did a great job in Southampton. Now he is the manager of Tottenham and it is a great challenge for him."
