World WBO super middleweight champion Arthur Abraham will defend his title with a rematch against German compatriot Robert Stieglitz on March 23. Abraham, 32, won a unanimous decision victory over Stieglitz in Berlin last August and has offered Stieglitz a rematch in his home city of Magdeburg, central Germany. \"For me it is a question of honour\", said Berlin-resident Abraham. \"Robert was brave enough to face me in my backyard. Now I am travelling to Magdeburg to face him in his.\" Stieglitz earned a rematch with a third-round knock-out of Poland\'s Michal Nieroda in Barcelona on Saturday and is now focused on winning back his title. \"Somehow I wasn\'t able to fight to my full potential during my first fight against Arthur,\" said the 31-year-old. \"After I suffered cuts, I couldn\'t get back into it. It just was not my day. But that will not happen again.\" From AFP
