The average high temperature in July in Qatar is 116.
Phoenix is 106
Jackson, Miss is 91.4
This is just flat out irresponsible from FIFA. In no way are they considering the safety of the players. To play a soccer match in 120 degree temperature is absurd.
And air conditioning in these proposed stadiums will help fans, not players.
What really matters here is that players give all of their effort to win the cup and to provide good entertainment to the assistants. No one will ever be agree with the country that host the WC.
