Right, because that's never happened in the history of football.....oh wait, yes it has.
Probably not on the grandest stage of them all, though, so
of course Griezmann isn't going to take the high road, and if the ref makes the mistake of awarding a free kick where there shouldn't be one, that's on him I guess. Lucky for Griezmann he was able to capitalize on the error and it ended up in the Croatian net moments later.
This isn't sour grapes or anything, by the way, as I said before I'm glad they won since it turned out to be a profitable event for me. My only gripe is with Griezmann, first for the "slip" that he sold as a foul, and again later for that obnoxious "L" dance he did in front of the Croatian supporters.
If the roles were reversed, and Modric had done that stupid dance prior to a Croatian win, you'd have been livid and rightfully so.
