I feel like I coach too much during matches

I’d give yourself a rule rather than telling yourself to “talk less”. For example, try the first five minutes with no football instructions at all. You can encourage, manage safety and help with a rule, but you do not tell them where to go or what action to take. Then notice what actually goes wrong without your voice. It is often much less than we imagine. You can also pick one theme before the match. If you are working on finding space, only intervene around that rather than commenting on every pass, tackle and shot. The uncomfortable bit is accepting that silence can still be coaching. You have prepared the players, set the environment and now you are watching what they can solve. You do not have to prove your value by being the loudest person there.
