I think they have 10 higher category and 9 lower category. Lower category tickets will be about £25 cheaper in the Trinity, based on last season.
At a guess, lower category will be Bournemouth, Brentford, Brighton, Burnley, Palace, Fulham, Leeds, Sunderland and one of Everton or West Ham. West Ham at home will be inexplicably televised of course, as is tradition.
