Sources at the Bernabeu say Schuster is confident deals could be in place for both players next week.
But a potential sticking point could be Ballack's incredible £130,000- a-week salary - steep even for a club the size of Real.
The Spaniards have been chasing winger Robben for more than a year and are offering him a five-year contract.
Ballack is believed to be considering a three-year deal with the option of a fourth year.
Schuster said: "I would be delighted if the club succeeds in signing me Ballack and Robben."
