Bild says Toni has been suspended by Bayern Munich following his critical remarks about coach Louis van Gaal.
"I have had problems with him for four months now and there is a limit to everything," he added in an interview which is likely to have consequences for the 32-year-old.
"We cannot accept this behaviour and we have made that clear to him," said Van Gaal.
Whether that is the end of the issue remains to be seen. Van Gaal expects further disciplinary measures to follow.
"That is up to the board," he added.
