土媒：加拉塔萨雷有意冬窗引进格雷茨卡，在研究如何免签（土媒：加拉塔萨雷有意冬窗免签引进格雷茨卡，正研究操作方案）

Summarizing transfer interest

I see the user is asking about a headline in Chinese regarding Galatasaray's interest in signing Leon Goretzka during the winter transfer window, specifically about signing him for free. I should provide a brief summary and context around Goretzka's contract status at Bayern Munich, which extends to 2026. This means he wouldn't be available for a free transfer. I’ll also touch on transfer mechanisms. Winter window is in January, and it must be clear that he’s not free to sign.Analyzing Goretzka's transfer rumors

It seems that the idea of signing Leon Goretzka for free is quite dubious. The only way would be a loan with Bayern covering wages or mutual termination of his contract, which is unlikely. Bosman transfers don't apply since he isn't in the last six months of his contract, which runs until 2026. I should also mention the varying reliability of Turkish media. Galatasaray may need midfielders, and it's worth noting Bayern's situation under Tuchel as of 2025. Goretzka has been a strong performer, and despite past exit rumors, he stayed at Bayern.Providing quick summary in Chinese

I see the user likely wants a quick overview in Chinese, so I’ll provide concise bullet points as per the guidelines.

1. 简述：土媒称加拉塔萨雷想在冬窗引进拜仁中场格雷茨卡，并研究免签方案。
2. 可行性：格雷茨卡与拜仁合同至2026，非自由身，冬窗免签基本不可能。
3. 现实可能路径：包括租借、转会费低价等。
4. 可信度：土媒传闻需等待德媒（如Bild、Kicker）验证。
5. 加拉塔萨雷方面：薪资负担高，格雷茨卡工资较高，难度大。

If the user wants sources, I can track that.
