求翻译：另外，出于我的好意，建议你的朋友们最好佩带护腿板，因为在球场上，人们总是争强好胜，不管比赛之前说多少友谊第一，比赛第二的话！等比赛开始，一切都不会按最初的设想一样去发展！是什么意思？

Also, out of kindness, it is recommended that your friends the best wear Shin protection, because on the pitch, people always competitive, no matter how much said before the game the friendship first, competition second! Competition begins, all is not as envisaged in the initial development!
