I understand your point of view, but the GK went out for the ball, missed it, and took the man down in the process; how is that not a penalty? Running into a striker without making contact with the ball is a straightforward penalty. Didn't you notice how quite the GK was? He never protested because he knew what he did was wrong; if VAR had intervened, it could have resulted in a red card, which is why the Croatian players did not push for it. They were aware that it was a penalty and accepted their fate
He didn't run into him, he actually stopped just before Alvarez reached him. Anyway, I don't think it would have been the same decision if it wasn't Argentina on the other side.
Regarding players not protesting, I don't know how you missed bunch of our players complaining to the referee and Kovacic even got yellow card because of that.
As I said before, they were better and our team didn't show much this game but before that penalty they did nothing and if it weren't for that it would have been much closer game.
