I imagine it will be a great day all over Englund and South Africa.
I am disappointed NZ did not climb to its potential but as a New Zealander I think the All Blacks are part of the country's identity so much that you got to be grateful for those guys' mahi and all the competition along the way and admin along the way from regular ppl which helps to make those men so great.
Any New Zealander knows those Saffas in a world cup final will be a formidable formidable beast so regardless of who you think should win on form (Englund)
based on history and the history of what YOU KNOW, it would be a great surprise to me if SA lost.
Great day for sport and should be a hell of a ride for both countries. Enjoy your day with family.
