Bayern Munich president Franz Beckenbauer fears losing two of their best players to Real Madrid.

Having already expressed concerns over Real's pursuit of Bosman prospect Bastian Schweinsteiger, Beckenbauer also admitted Franck Ribery could end up in Spain next season.

"His contract only runs to 2011," said Beckenbauer. "If they (Real Madrid) were to make an offer, we would be in a weak negotiating position."
