They are making a big deal about goal line stuff and trying to find reasons to not do it because if they can use technology for the goal line it won't be long before everyones asking why they can't use video replay for everything.
Its daft, video replays are a stupidly easy to implement technology, the prem league games are already filmed with replays done quicker than the ref needs them and 99% of the incorrect goal line decisions have been caught on camera.
A small smartphone like device and screen if they wanted it to be direct to the ref in seconds would be viable these days, costing far less than the wages of 2 extra and entirely useless ref's they put in. Costs being too high, lol, the fact that the referee pool and wages are so low when there are so many billions involved in football is already laughable, talking about big costs for technology when we're talking about a few thousand per club for goal line, and essentially the cost of a tablet/smartphone for replays as most of the people involved are already being employed at the games anyway.
Tablet, link to footage, a back up screen/tablet on the touch line and hiring a few people to inspect and check on the guys doing the replays so some fan of a team working in the editing booth doesn't leave out a particularly incriminating replay... job done.
Completely fair football, with 99.9% of game changing decisions being made correctly within days of implementation, in leages worth billions, and costs in the low millions to implement across the big leagues and all champs league games... laughable excuse.
Honestly the longer they refuse to really talk about video replays, the more bent football appears.
