Mauro Icardi has launched legal action against Inter Milan.
The striker is suing for 1.5m in damages to be let back into the squad.
Icardi had been told when Antonio Conte took over this summer that he was not in their plans and his Number 9 jersey was handed to Romelu Lukaku.
He was instead given the Number 7.
Corriere dello Sport reports Icardi intends to call on teammates to testify in front of the tribunal.
Published extracts from the legal document show he alleges the club took clearly discriminatory" action against him.
