BERLIN - Schalke's Kevin-Prince Boateng promises there will be no love lost when he comes up against half-brother Jerome Boateng in today's Bundesliga clash with Bayern Munich.
Defending champions Bayern, second in the table to Borussia Dortmund, are at Gelsenkirchen's Veltins Arena to take a Schalke side that has won its past four games after a poor start.
Since his arrival from AC Milan last month, Kevin-Prince has helped lift Schalke up to ninth.
The Ghana international has added steel to their attacking midfield and the 26-year-old also scored the winner at Mainz in last Saturday's 1-0 victory before hitting the second goal in Wednesday's 3-0 Champions League victory over Steaua Bucharest.
"He is my brother, but there will be no love lost in the game," said Berlin-born Kevin-Prince.
"I have already told him I would be disappointed if he didn't go at me 100 per cent 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, who is younger by a year and plays for Germany, is aiming for another three points.
"I'll try and do that without bringing him down, but if there is no other way, I'll do it," he said.
"He won't run away from me."
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.
Bayern midfielder Javi Martinez missed training on Thursday and Friday for a dental operation, while Germany midfielder Mario Goetze is training after an ankle injury.
Both will miss the game, although vice-captain Bastian Schweinsteiger should feature having come on in the win over Moscow.
Schalke are still without Netherlands striker Klaas-Jan Huntelaar, who is recovering from a knee injury, with Hungary striker Adam Szalai deputising.
Dortmund heads to Nuremberg looking for a sixth win from six but centre-back Mats Hummels is rated highly doubtful.
Hamburg host Werder Bremen with caretaker coach Rodolfo Cardoso in charge after Torsten Fink was sacked in the wake of last Saturday's 6-2 drubbing at Dortmund.
