I don't think it needed changing, although I've long felt that away goals should no longer count after 90 minutes of the second leg. That was the simple solution to one of the problems cited.
Away goals adds drama and excitement. Of course they want to get rid of it.
Surely if you were going to scrap it then it should have been done last season when some teams weren’t playing at home due to Covid but could still go out on away goals?
