Isn't that a recurring rumour?
It may be an old rumor. I'm not sure which one is the current issue.
Oliver Kahn, has just announced that Bayern are not interested in signing Haaland but are looking to extend Lewandowski's contract.
It seems an official announcement from Bayern Munchen. So, Haaland possibly doesn't move to Bayern, his destinations will be Real Madrid or Manchester City. But we don't know how big the chance for him to leave Dortmund is. Manchester City wants to focus on signing Harry Kane, while Real Madrid will sign Mbappe. This can make the two clubs to decide stop signing another top striker because of the financial limitation or too many having strikers. Haaland has a possibility to stay in Dortmund next season.
