I usually ask the managers if they have any questions first. Makes a chance from the same old stuff they get every match - I then say something like keep the benches tidy, subs let me know, and if you need to speak to me about anything give me 15 minutes after the game I’m more than happy to chat (that’s one of our league rules).
Club assistants:
Left back, please do ball out of play and offsides, leave everything else to me.
Captains:
Any questions - keep it short and sharp if you need to talk to me, I will try and use you if I can so work with me. Toss.
