"David told us that he wants to listen to the offer," said Dortmund press spokesman Josef Scheck.

Betis sold Spanish international wide-man Joaquin to Valencia for 25 million euros in midweek and want Odonkor as a replacement for a reported seven million euros.

The 22-year-old Odonkor, renowned for his electric pace, was a surprise late inclusion in Germany's World Cup squad with Juergen Klinsmann calling him in despite the Dortmund man being uncapped.

Odonkor was often used as a substitute on the right flank and caught the eye as hosts Germany finished third after losing 2-0 to eventual victors Italy in the semifinal.
