The FA don't give a crap about any team outside the top half of the Premier League.
The Top Clubs: "
We don't want replays"
The FA: "
Okay"
The FA: "
Will you give extra money to lower league sides?"
The Top Clubs: "
No"
The FA: "
Okay"
The FA: "
Would you like to tickle our tummy while we roll over and submit?"
The Top Clubs: "
No, now f*** off and wait until we next tell you what to do"
The FA: "
Okay"
The FA & Premier League should grow a pair. Tell the top clubs who want to, to f*** off and form their European Super League.
BUT no playing in domestic cups, and no relegation/promotion out of it. I reckon within a decade of American Football style, no promotion or relegation, the European League would simply be a TV attraction for Asian & North American fans, while European fans will move away from it, back to their own domestic leagues. European Cup & Champions League for Europes domestic sides.
It will never happen of course. So the life will continue to be sucked out of the game.

As a realistic option [
that also would never happen]. Before each tie, both clubs are offered the option of forfeiting the game if level after 90 minutes. This year, if Spurs had decided they didn't want a reply, they'd have gone out and Tamworth would still be in the competition. Or, Spurs would have rejected the option, and had a replay. Clubs decide what they want and face the consequences.
