- Leroy Sane completes Bayern Munich move
- Birmingham's Jude Bellingham headed to Borussia Dortmund - report
Pictures of Sane joining Bayern were posted on Bayern's Arabic website on Thursday night, before the club officially announced the 24-year-old in a deal believed to be around €45 million plus add-ons on Friday morning.
According to Sky Sports, Bayern have apologised to City for the error.
Sane, who is expected to earn around £350,000 a week on his return to Germany, scored 39 goals and made 45 assists for City after joining from Schalke for £37m in 2016.
The Germany international is expected to start training with Bayern next week, but is not allowed to feature for them in the Champions League's resumption in August.
