There needs to be changes made to the format of the FA Cup. 

I would have Premier League teams enter the competition from the first round. I would bring back replays for the first four rounds, so lower league clubs can earn more money from that replay.

I would also fine Clubs for not picking their strongest team.

I would go back to having all FA Cup matches played on a Saturday, with a number played on the Sunday, to encourage higher attendances. Only replays would be played midweek as they used to be in the past.

I would also reduce the number of live TV matches that are made available to try to encourage higher attendances at those FA Cup matches.

Some good ideas there @Robbie, but I quite like the big clubs joining in in the third round. That way, a big draw in round three is a reward for progressing, rather than a lottery. But replays should definitely return and I'd also look into fining clubs for fielding weaker teams - if it's possible in the Trophy, it can be done in the FA Cup too.

Poor attendances aren't new though. I remember us playing Cambridge at home in the early 2000s and there were less than 3000 people there. It was so quiet approaching the ground I actually thought it had been called off.
