This is professionalism

"AC Milan star Kaka says team-mate Dida was "wrong" to react the way he did after being struck by a Celtic fan.
The goalkeeper collapsed dramatically after being hit in the face by the home supporter towards the end of Wednesday's 2-1 defeat at Celtic Park.
He was eventually stretchered off but has been criticised for overreacting.
"He made his choice and we will support him even though what he did was wrong. It was a difficult moment for him," Kaka told the club's official website."

This is how big boys act and how big girls should act.
