Grifo has put pen to paper on a contract until 2021 at the BORUSSIA-PARK.
"Vincenzo Grifo has developed in a really interesting way in the last couple of years in Freiburg," said Borussia's sporting director Max Eberl. "He played a key role in their outstanding season and will make us much more flexible going forward next season. We're really pleased to be able to bring him to Gladbach."
Grifo scored six goals and returned eight assists as promoted Freiburg finished a remarkable seventh on their return to the top flight.
