Forest-Leicester ought to be either the Friday or Monday as minimal travelling and will sell out whenever. Although that's probably too sensible for competing TV companies.
I think Spurs-Brighton is nailed on.
Personally, I hope it's the Friday night game as the trains are screwed at the weekend. https://www.nationalrail.co.uk/service_disruptions/currentAndFuture.aspx?TravelDate=05%2F02%2F2022&TOC=sn
