Shanghai SIPG signing Marko Arnautovic has hit out at the media over the way he was portrayed at West Ham.

At his unveiling in Asia, the former Stoke City man hit out at criticism over his attitude and said he always gave everything to his previous teams.

"They do not train with me, they do not play with me, but they just write something," he said.

"Maybe that's the characteristic of European media, the truth is that I always give everything to my team, I never spare myself.

"I'm here to work hard, I want to do my part so the club can achieve all of its goals."
