Lokomotiv Moscow midfielder Joao Mario has taken aim at parent club Inter Milan.
Mario has been on the books at Inter since 2016.
“I could not train or play in friendly matches like everyone else," Joao Mario told A Bola.
“I trained alone with Mauro Icardi. I don't understand their position, because Inter paid €40m for me and treated me like a kid. It was despicable.
“I found a less stable club than Sporting CP; a lot of confusion, change of coaches, a badly prepared season.
“I'm sorry that much more happened off the pitch than on it."
