Boateng insists the Blues midfielder's slap was worse...
Boateng picked up a yellow card in last weekend's FA Cup final for a foul which has ruled Ballack out of the World Cup with ankle damage. The midfielder had been slapped by the Chelsea midfielder before he launched into the tackle.
Although he had issued an apology, on Wednesday he insisted Ballack's attack was more serious.
"There is my foul on the one hand and his slap on the other, and I think that violent conduct is far worse than a foul," Boateng told Sport Bild.
"Ballack really does surprise me. He complains for weeks when [Lukas] Podolski slaps him and yet he does it himself. He is no better than Podolski. What kind of behaviour is that?"
Boateng also criticised Germany coach Joachim Low's comment that his foul deserved a straight red card. Previously, Low had refused to criticise Ballack for slapping team-mate Lukas Podoloski during a match with Wales in April 2009.
"When I hear that, I can see that he has two different ways of seeing things," added Boateng.
"Can his captain slap whomever he wants? That was clearly violent conduct. If I had done that, I would have been banned for years. That is why I left the Germany set-up to represent Ghana."
Boateng can expect a hot reception when he lines up against Germany and brother Jerome Boateng in Johannesburg on 23 June. The German-born player switched allegiances to the African nation earlier this year.
