VfL Wolfsburg's Kevin de Bruyne wants to apologise to the ball-boy he insulted with a foul-mouth tirade during a German league match by offering him a signed shirt, according to a report.

German daily Bild claim the 23-year-old Belgium international snapped "Give me the ball, you motherfucker!" at a ball boy late in Wolfsburg's 1-1 draw at Eintracht Frankfurt on Tuesday before scoring the equalising goal.

De Bruyne's rant was audible on television and when a Bild reporter confronted him, the midfielder said he will give the youngster, who plays for Frankfurt's Under-16 team, a signed playing shirt.
