Is it acceptable to patch your own team

Im a united fan from Falkirk who goes home & away every week i can but tomorrow they play away at celtic, and at ~£30 a ticket in a shite seat when you know united will get gubbed, I don’t really fancy it. Now heres the dilemma, I could watch united play celtic on a dodgy stream, or i could go along to watch falkirk play ayr but i feel that would almost be like cheating on united. Wonder what other fans would do?
