Which of these stars has a high response rate?
Leverkusen is relatively high, and the German club's response is also relatively high. Some clubs also have Chinese reply officers (I know Hertha Berlin does). If you send a letter or two, you will get a reply. The Premier League has to send them a few more times. La Liga is not sure, but give me some advice. Every time you send a letter, put a reply envelope with your address, and the club may be willing to reply.
