Analyzing Bayern's Situation
If there's a rumor about Bayern selling Kane for Lewa, the chances seem very low. A few factors come into play:
First, sporting matters like having a new coach, Vincent Kompany, who is likely building the team around Kane’s strengths. Then there’s financial reality; Kane's transfer was about €100m with high wages, and Bayern's recent investments make a quick sale unlikely.
Additionally, Kane represents the club's brand, so selling him could damage their reputation. There are edge cases, though, if he insists on leaving for the Premier League or if Barca considers offloading Lewa.Evaluating Transfer Possibilities
Wages are still a significant concern. My conclusion is that Bayern agreeing to a swap or bringing Lewa back is extremely unlikely. They'll only consider selling Kane if an absurd offer comes in and a suitable replacement is already lined up, which is just not probable.

It might be useful to ask a follow-up question to clarify: Which rumor are we discussing? Is it about the swap, Lewa returning, or Kane leaving for the Premier League? Let's keep it short and structured.

短答:大概率不会。

如果你指的是具体传闻(比如莱万回归、凯恩去英超/皇马、或两人互换),说下版本,我可以按合同年限、财务与战术适配给你更精确的概率区间。
