Villa were the last tie to be drawn for some reason.
Pressumably because they were one of the last 2 balls?
Well, it's clear the Villa ball wasn't touched till the end because it's number 1! it's first in but then second to last out!
So in between the drawmasters Redknapp and Nolan haven't touched the bottom of the bowl and left Villa till last.
It's a poor shuffle, and the system can be manipulated when there isn't the correct shuffle. Hustlers do this in cards.
I don't think any shenanigans went on other than a very poor shuffle system which didn't include the number one ball being touched till the final draw.
