I don't count Ruud or Sverkos because the original corner/free-kick didn't work and was cleared.
I make that only Russia to score from a free-kick or corner out of 16 goals?
You could argue new balls or the fact that international teams don't get as much preparation time but there were no goals like this in the CL final or semi's - Adebayor and Hypiia in the QF's but it still seems very little.
Are teams just too organised to concede this way?
