However, the Germany international concedes anything can happen in the future.
Asked about his time in Italy with AS Roma, Rudiger said: "Italy was very important to me in the past, I learned a lot on a defensive level.
"And then I liked life, like the food: in Italy there is the best pasta and the best food. There are clubs like Roma, Napoli, Juventus, Inter, Milan, big important clubs.
"In football you never know, but I am very happy with where I am and I don't think about where the future will take me."
