The coach of your school team might not have any influence over whether or not you get a trial with a particular club. If you are contacting an English club, contact them through email or phone. You can visit their website and find out who their youth recruiters are, which will help with finding their email addresses. You can also try contacting their academy manager or head scout if there is no email address on their website.
