Leroy Sane will have surgery after Manchester City confirmed he damaged his ACL - likely ending a possible move to Bayern Munich, reports SkySports.
Sane injured his right knee in the opening stages of City's Community Shield win over Liverpool at Wembley Stadium last weekend.
City said the winger underwent testing throughout the week, with a specialist doctor travelling to Manchester for further examinations to understand the extent of the injury.
The club confirmed he will have surgery in the coming week.
