I watch football after my evening shift, but my friend's messages spoil the result. Is asking for silence too much?

My phone lit up with "WHAT A FINISH" while I was closing at work. I hadn't seen the match. Even without a score, I now knew something dramatic had happened late on.

I usually watch the recording when I get home. My friend watches live and sends goals, reactions, and occasionally just a face that tells me exactly how our team did. I've asked him not to send the result until I say I've finished, but he thinks discussing it is part of supporting the team together.

I know I can't expect the whole world to wait. This is one direct conversation with someone who knows I'm watching later. I could avoid his messages on match nights, though I would miss ordinary conversation too.

How would you make the request specific enough that "I didn't say the score" stops being a loophole? I still want to hear what he thought, just after I've had the chance to experience the match myself.
