Shkodran Mustafi admits he is unsure about his future at Arsenal.

The mistake-prone defender has shown signs of improvement under current boss Mikel Arteta.

But with his contract set to expire next summer, Mustafi says he would be interested in returning to his native Germany.

"The Bundesliga is always interesting for me," the Germany international told Sport Bild. "In terms of sport, it has made great progress. It's also my home."

"In the current situation, it is difficult to predict how the transfer phase will go."
