I believe its Fifa's decision, theres definately plenty of competition for places this time around which is always healthy to see, apart from Germany where it seems Siebert is a dead cert, Same with Holland and Makkelie.
Spain is very competitive with three candidates there, my personal preference would be Lahoz, But It wouldn't shock me if its Del Cerro Grande. France have got two nominees surprisingly, Turpin is surely nailed on however.
I think its gonna be very tight between Oliver And Taylor, Though if I had to guess at which one would go, I'd Say Taylor.
