It is difficult to predict which team will be the world champions right now. Before the World Cup, many considered Argentina and Brazil as the favorites for the World Cup. But Argentina lost their first match. We are getting expected good performance from renowned teams. So it is impossible to predict which team is going to be the champions before the first round is over. But it is easy to understand that Asian teams are not as strong as American or European teams. However, even if Asian teams do not have star players, their team bonding is excellent. So Asian teams should not be neglected.
what you say is true, it's hard to guess who will win the world cup this time, surprises happen everywhere, even in the last match Portugal vs Ghana, we saw surprises happen at the end of the match, 5 goals were scored there (3 goals Portugal and 2 goals Ghana). Asian teams win are not so favored compared to teams from the Americas or Europe but surprises can appear in this world cup.
