Exploring overseas games in football
I’m looking into the Premier League's idea of having a "39th game" abroad back in 2008, and La Liga's attempt to hold a Girona vs. Barcelona match in Miami, which was blocked. The Bundesliga is considering U.S. matches, but they seem cautious after recent protests against commercialization. It aligns with Hainer's comments on fan sentiment. I could provide a summary of his remarks and the overseas games debate, then ask how the user would like to proceed.
你这是条新闻标题。大意：
- 拜仁慕尼黑主席海纳表示：德甲应扎根本土，反对把正式联赛放到海外举办。
- 背景是英超/西甲多次探索海外联赛或杯赛以拓展市场，但德甲球迷团体近期强烈反对过度商业化（如对投资引入的抗议），海纳此立场与本土球迷情绪一致。
- 这不影响季前商业巡回或友谊赛；核心是“正式联赛不出海”。
需要我：
- 翻译全文或做英文版摘要？
- 补充这番话的出处与完整原文？
- 解析对德甲商业化、转播与球迷关系的影响？
- 对比英超“海外第39轮”、西甲迈阿密计划等案例？
