Schalke 04′s Kevin-Prince Boateng has promised there will be no love lost when he comes up against his half-brother, Bayern Munich centre-back Jerome Boateng, in Saturday's Bundesliga clash.
Bayern, second in the table behind Borussia Dortmund, are at Gelsenkirchen's Veltins Arena to take on resurgent Schalke, who have won their last four games after a poor start.
Since his arrival from AC Milan last month, Kevin-Prince Boateng has helped lift Schalke up to ninth with the Ghana international adding some steel to their attacking midfield.
The 26-year-old scored the winner at Mainz last Saturday in a 1-0 victory and hit the second goal in Wednesday's 3-0 Champions League victory over Steaua Bucharest.
European champions Bayern will provide an acid test of Schalke's winning streak, but there promises to be fireworks when the Boateng brothers clash.
“He is my brother, but there will be no love lost in the game,” said Berlin-born Kevin-Prince Boateng.
“I have already told him I would be disappointed if he didn't go at me 100 percent during the game. I will be doing the same.”
Bayern have dropped just two points from their first five Bundesliga games and opened the defence of their Champions League title on Tuesday with a 3-0 win at home to CSKA Moscow.
Jerome Boateng, 25, has said he will be hoping to leave Gelsenkirchen with three more league points and will not take a backward step against his sibling.
“I'll try and do that without bringing him down, but if there is no other way, I'll do it,” said the Bayern star.
“He won't run away from me.”
Bayern travel to north-west Germany from Bavaria as clear favourites, but Kevin-Prince is defiant.
“For the game in Schalke, anything is possible.”
The last time the brothers played each other was the 2010 World Cup group stage match when Germany beat Ghana 1-0 in Johannesburg.
“It's a big thing for us that we can play against each other at such a high level,” said Kevin-Prince.
