Once he steps onto the football pitch, Borussia Dortmund and Japan midfielder Shinji Kagawa is locked in.
He takes no prisoners - not even if you're a child.
Kagawa demonstrated this in a video posted on Twitter, where he nutmeged a young boy to the point where the child cried.
It was effective though, as when Kagawa went to comfort the boy, he ran to the ball and kicked it away.
