The Spanish giants want football's best-known middle-man to try to negotiate a deal with Manchester United. And Roo is one of Real chief Florentino Perez's top summer targets.
A Madrid source said: "Zahavi has been told to do all he can to try to bring Rooney to the Bernabeu. The club are confident a deal can be done."
Speculation about the England striker's future has intensified following revelations about United's precarious finances.
Perez, who signed Cristiano Ronaldo from United in a world-record £80million switch last year, normally gets what he wants.
Employing Zahavi shows Real are serious in their pursuit of Rooney, 24.
Zahavi is the go-to guy for all major deals in world football.
The Israeli, who also represents Rio Ferdinand, was the man who brought Roman Abramovich to Chelsea.
Nothing less than what United received for Ronaldo.
