Real Madrid target Khedira hands in Stuttgart transfer request
His agent Jorg Neubauer confirmed his client's intention to make the move, but the two clubs must first agree on a fee.
Stuttgart chief Fredi Bobic has confirmed that the player has asked to leave.
"Khedira has informed us that he wants to go to Real," he told the Bild newspaper.
"We now have to find a solution."
Khedira has one year left to run on his contract with the Bundesliga side, but Bobic will not try to force him to remain.
"We respect Sami's decision," he added.
"I know that Stuttgart is close to his heart, but Real don't come calling every day."
