Former Arsenal midfielder Mesut Ozil is undergoing a back operation this weekend.
The 33 year-old left Fenerbahce for Istanbul Basaksehir this summer.
He announced: "Unfortunately I will be out for a longer time.
"I will be undergoing a surgery this weekend to finally get pain free in my back again.
"I will try everything to get back on the pitch as soon as possible again. Thanks for all your love & support."
