1) Qatar has faced strong criticism due to the treatment of foreign workers involved in preparation for the World Cup.
2) Amnesty International is a non-governmental organization which focuses on human rights and has referred to forced labor and stated that thousands of migrant workers have died as result of human right abuse.
3) Weather of Qatar is so hot that FIFA has shifted the schedule of the world cup to November which will disturb the domestic league and players will not get much time to rest.
4) A football fan would never miss one of the most important events so the problem rises here. Qatar is so expensive and there are many luxury hotels which cost a lot and will restrict fans from attending the world cup.
5) There might be empty stadiums, it’s not only expensive but also the locals are not much interested in attending sport events. Example to this is the average league attendance in Qatar is less than 700.
