4-0 would be good - a win for Nigeria would make the group really exciting as Korea and Nigeria play each other in last game and only one of them can go through...
i watched Greece's first game as well, i think they will take a hiding here.
There is a chance of at least a 3-0+ , but more than likely just a 2-0 win for Nigeria. I think the Greeks are among the 3 weakest teams at the world cup...no prizes for who the last one is if SA is one of the others
