Argentina is better than Croatia but the world cup is too hard to predict. The world cup is full of surprises, I don't Croatia as a weak team, despite Argentina is a strong team they can make a mistake that will give Croatia to win.
The world cup is really difficult to predict, weak countries are really surprising us by winning the strong once, Argentina is having higher chances of winning the match, but Croatia have being surprising everyone in the world cup, any little mistake Argentina make, they might lose the match, Croatia players are really dedicated and they will try their possible best to win Argentina, it will be a tough game for the two countries, but I think Argentina should win the match.
