Fact-checking selection policies
Given the uncertainty, I should ask for the date or source to clarify things. It's actually not accurate to say there’s a general requirement for players to leave a club. Coaches in Germany focus on form and fitness instead. For instance, during the 2014 World Cup, players like Podolski and Klose were backups but still made the team. While match rhythm is key for goalkeepers, like Trapp being a backup yet selected, Leno remained with Fulham and wasn’t picked for the 2022 squad.

这是个很“标题党”的说法。就公开信息与国家队一贯做法来看,“必须离队否则不带去世界杯”的硬性最后通牒几乎不成立。
要点
如果你有具体来源或时间点(文章链接/采访日期/哪位教练说的),贴一下我可以帮你核实原话与上下文,区分是媒体解读还是教练原意。
