Former Germany international Dennis Aogo has joined Stuttgart from Schalke on a two-year deal.
The 30-year-old left-back has also played for Freiburg and Hamburg and has made a total of 213 Bundesliga appearances.
"I didn't have to spend much time considering the offer from VfB and I am very happy that the transfer has worked out," Aogo told Stuttgart's official website.
"I am very motivated and extremely eager to get on the ball and begin training with the team.
"During the course of my career I have played in Stuttgart on a number of occasions, so I know there is always an unbelievable atmosphere here. That too was an important factor in me making this move to VfB."
Stuttgart director of marketing and sales Jochen Rottgermann added: "In Dennis Aogo, we have secured the services of a nationally and internationally experienced player, who has proven his qualities wherever he has played.
"He knows the Bundesliga very well and will thus need little time to get integrated. We are very happy to have been able to convince him of the direction we are taking."
