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.
That's right a little mistake will become good opportunity for Croatia maybe also for Argentina, the match will look tough. If see at the previous world cup, Croatia won successfully against Argentina with a score of 3 In that match Argentina could not score. It could be that tomorrow match Argentina will take revenge or Croatia will be able to secure a ticket to the final. Unpredictable matches.
