Manchester City manager Pep Guardiola has revealed that Leroy Sane is likely to be sidelined until February at the earliest after tearing his anterior cruciate ligament.
The German is set to have surgery on the injury which he picked up in the early stages of City's Community Shield victory over Liverpool, but such an injury often requires a lengthy spell out of action.
Speaking ahead of City's meeting with West Ham (via BBC Sport), Guardiola confessed that he is not certain how long Sane will be unavailable, although history suggests that he will miss the majority of the Premier League season.
He said: "It is incredibly bad news. I don't know how long he will be out. Normally this kind of injury is six or seven months - hopefully February or March."
The club previously confirmed that Sane would work with a specialist to try and aid his recovery, adding that they will offer him plenty of support until he feels able to return to action.
As a result, the 23-year-old will likely remain at the Etihad Stadium for the coming season, and City will be hoping to see him return as soon as possible on their quest to compete in every competition next season.
