The cost is a factor as are ticket prices and the timing of the game. For many the thought of spending £100+ and arriving home late on a Sunday night outweigh the fact it is a semi. The sooner the halfwits at the FA move these games back to neutral venues and on Saturdays at 3.00pm the better. And no doubt the final if we reach it will be at a stupid time on the Saturday afternoon and we can have half of these arguments all over again
