Whilst Blatter may have gone, have we seen anything to suggest that FIFA has cleaned up its act? It's still the same grubby, you scratch my back, I scratch yours organisation it always has been. Smaller nations who will never qualify nor host the tournament get hefty backhanders for siding with the right sorts. Bearing in mind the practices that landed us with Russia and Qatar getting to host the World Cup, I genuinely wouldn't bother. How the FA and co managed to spend over £2m working that out is anyone's guess ...
UEFA are hardly beacons of virtue but they're more malleable as they have fewer members to turn to to host a tournament. A UK/Ireland bid seems sensible in the circumstances.
