Bayern have not kept their pursuit of the Man City winger quiet by any means after embarking on an intense charm offensive this summer to try and capture Sane, reports the Manchester Evening News.
But City are now waiting to discover the full extent of Sane's injury after he was substituted after just 10 minutes in the Community Shied after twisting his knee.
It seems that Bayern are now remaining as quiet as possible about Sane, as Hoeness only had a brief response when asked if the potential injury had put an end to any potential deal.
"Ask the English. We will announce facts," Hoeness told Bild.
He was then asked if he was confident about the signing, to which the Bayern president simply said "bye."
