I think the penalty was a correct call to be honest. The ball traveled a long distance, and Persic's hands were not in a natural position, so for me , it was a penalty.
France grinded their way to this WC. This makes up for 2006 though, when France played some really beautiful football and Zizou enchanted football fans every game, and then they ended up losing it to a cynical Italian side. This time France was the cynical team, and while it isn't my favorite style to watch my teams play, nor do I think France with the talent at its disposal needed to play this way, nor was I DD's biggest fan prior to this WC. But it worked for him, and he's a world champion, so you have to give the guy credit.
Both Belgium and Croatia played this WC's best football though. I thoroughly enjoyed both those team's games. Modric and Hazard were for me the two best players in the tournament by far, so a completely deserved award for Luka, who in my opinion is one of the best, most consistent and most complete midfielders I have ever watched.
