Reports have suggested that the Italian could now be on the way out of the Etihad Stadium following the latest bust-up.
However, Platt has said that he is at a loss to explain why Balotelli stormed down the tunnel when he was replaced by Sergio Aguero.
"I don't know why he walked down the tunnel. He wasn't injured," said Platt.
"Should he have walked straight down the tunnel? No."
Balotelli has been involved in a number of controversial incidents during his time in England.
