The ex-Arsenal skipper is currently in his second season at Bayer.
Bayer Leverkusen midfielder Granit Xhaka could yet return to Swiss football.AdvertisementAdvertisementAnd his brother, Taulant Xhaka, said a return to former club FC Basel could be on.
He told Blick: "It could work. There is a plan. I won't say any more.
"I, too, would like to complete the coaching training course like my brother. The idea would be that Granit would become head coach and I would be his assistant. I see myself more in this role, in communication with the players."
Granit's deal with Bayer runs to 2028.
