Because their teams are good enough to lift the title, yet they lost vs the underdog teams which was shocking for them, their fans and citizens! Additional reason for CR7 is the fact that this is his last chance to play World Cup and lift the Cup. It ended as a catastrophic end for him and his team. Less than 24 hours for the match between Argentina and Croatia. I wonder if Croatia will add another surprise in this World Cup.
Croatia may well present a surprise, because Argentina does not look so invincible and its success is based on the efforts of only two players, Messi and goalkeeper Martinez. But Messi's contribution to the team's success at this World Cup is still much greater. It's hard to imagine what the Argentine national team will be able to do if this day is not Messi's day. Therefore, Croatia has a fairly real chance to reach the final of the tournament again.
All the players of Argentina team play very well but if we say that Messi plays very well in Argentina team then it will be wrong for us because if all the other players play bad then Messi can never do anything by playing well alone. I mean All players play a big role in a team but I see above all if the goal keeper is bad then the team can never win.
