Jonny Wilkinson is the man that dictates the game for England, they are useless without him as has been seen in their performances since the last World Cup, and since his return.
England could come into this game, with a point to prove after loosing so poorly to SA a few weeks back, but it seems to me that SA is the on form team.
However this world cup has been full of surprises, the pumas beating the French, England going down 35-0 to SA, Ireland going out at the group stages, so who knows, Its gonna be a great game!!!
