They definitely saw the halftime score of Peru/Australia and decided that they didn't have to try anymore.
Wouldn't normally pull for them but I'm all in on Nigeria. We don't need yet another traditional power who's playing like crap getting through. There's enough of them already in or likely in.
I wonder if Nigeria will regret wasting all this time when they're down a goal... Argentina must be so happy this is the tactic Nigeria is ok with today.
