With the money generated from bt sport, I think the club need to cover or at least contribute towards match tickets or travel. Could see us only taking a couple of hundred up there, not what the FA cup is about! The southampton Twitter page is the best bet for getting across to the club about subsidizing costs
Coaches are booked with Collesium directly, so i'd suggest Saints make no money from coach travel. Though they must get some kind of payment from Collesium to advertise them as the official operator. I was surprised this game got booked for TV until I found out 5 of the 8 games are being televised. Tough for the fans and I do hope the club do as you suggest and buy up some coaches or even better heavily subsidise the cost of the tickets so it benefits all fans and not just those who live locally. £10 for an adult say. Pretty disgusting kick off time for the longest journey, but it's all about the TV
