Fair point. But if you are a non-league player I think you'd prefer the chance of playing at Old Trafford in a replay than beating them at home on pens, personally.
They honestly might as well just scrap the FA Cup. If a small club can't battle to a draw at home to a big club and then go to their place for a big payday, then what's the point in the early rounds of the competition? The whole 'magic of the Cup' has gone. Might as well just make it for the top...
