"Yes, if not at Arsenal then maybe at FC Basel when he returns to Switzerland. It is my dream to play with my brother again. But whether that's at Arsenal or Basel, it does not matter," he said in an interview with Goal.com.
"I believe that he wants to return to Basel at the end of his career because he grew up here and FC Basel is his favourite team. As soon as he has two days off, he comes to Basel and visits his friends and family. There is a very strong bond.
"There are many nice moments. Of course, I like to remember my Champions League debut at Old Trafford at Manchester United, where we drew 3-3. Being able to experience this together with Granit in the same team was a very nice experience for us. As kids we used to spend 24 hours together."
