I wrote the book on wummery. In fact, most wums on this board are little more than disguised plagiarisms of stunts I was pulling two or three years ago.
Iceland are excellent and won quite a difficult qualifying group including Croatia, so yes I can see them getting 4 points and maybe 5.
Not surprised at the result, other than the attacking force - which doesn't seem to work well togethere - Argentina got **** all about them. Croats are a really well balanced side; good keeper, decent defence, world class midfield and good striking options. Definite dark horse for the competition, the last opportunity for their golden generation as well so they may surprise a few.
