"Man Utd" coach Jose Mourinho's decision to send safety Bastian Schweinsteiger to the reserve team was met with a response from the latter's brother.
"No disrespect," Tobi wrote on social media.
It is said that the player, who is not needed by the Portuguese, received a threatening message that his career at Manchester United is not over any day, but on his birthday.
The recently retired player from the German national team will not play in serious matches until he moves to another team.
The veteran is already being followed by two "Serie A" teams - "Milan" and "Inter".
