Being a host will give them the chance to be in the world cup playing against the teams but in fact when the team is not ready for the world cup and they are not really qualified normally they will just lose all the games and leave the World cup fast, just like what happened to Qatar and it doesn't matter how much money they spend for the world cup.
It is very important that every host should not just focus on preparation on physical structures but they should also prepare a food team he will feature in the world cup. This because early exit of host nations usually have a negative effect on the competition. The stadium will start becoming empty immediately the the host nation is knocked out and it will look as if it was because they wanted to qualify for the world cup that was why they hosted the competition.
