Its all very well saying all that, but the 20 fans i mentioned was the only few i knew,they will be considerable more not going for the same reason i.e. friday evening bad day to play, its all very good being only £10 in but what about the fuel cost's its gonna cost & like bulldogtrev pointed out its week before monthly pay & so soon after xmas, fans just cant afford it, & as for the gate recieved don't forget all expences come out of that, i.e. officials fee's, stewards fee's, players fee's backroom staff fee's. i realy want to see this game aswel but my shop doesn't close till 7 & im sure with this deal playing saints is part of the walmsley deal, it could of been pointed out aswel in the deal that the game be played on a sunday so all fans of both teams get to see there players out on the pitch.
Costs would be the same regardless of where it was played surely? Players do not get paid for friendlies AFAIK it is seen as a training session and a chance to stake a claim for a starting place.
Saints play all of there home games on a Friday, and have done for a long time so their supporters are used to Friday evening kick offs so why upset the apple-cart for the majority of fans likely to attend the game? You also speak of travel costs putting people off attending, but would this not be the same for the Saints fans travelling to the Mount and as stated earlier there are likely to be 10 times more of them than us.
