The side drawn at home should always have the advantage . if a tie goes to a replay, and then drawn again, the side drawn away currently get an additional 30 mins and then pens at their stadium giving them an obvious advantage to go through, so yes, I think the change is correct.
This is all well and good, but what if he has had a look, and decided that none are Championship standard, and maybe never will be? Just a thought. Maybe Scott, Semenyo, Conway and Bell were the last of that generation.
