The man whose penalty guided Australia to the 2006 World Cup believes Qatar's steamy weather will prove a major hurdle when the nation hosts the tournament in 2022.Former Socceroo John Aloisi, whose famous spot-kick in the playoff against Uruguay ensured Australia a spot in the World Cup in Germany, admitted he was stunned by Qatar's success in the bidding process.Multi-lingual Aloisi has been heavily involved in the Australian bid as a bid ambassador, and also featured in videos promoting the nation's merits to host the World Cup.While Australia enjoys winter when the tournament would have been held, temperatures in Qatar in June and July soar into the mid-40s daily, and only drop to the high 20s or low 30s at night."The conditions in Qatar - they've got the air-conditioned stadiums - but I don't know what the spectators are going to do during the day in 45 degree heat," said Aloisi, who now plays for A-League club Melbourne Heart."They won't be able to set foot outside, they'll have to stay indoors."It's a tough one but I'm sure they'll make it work.Aloisi admitted he was devastated Australia missed out, effectively ending any realistic chance of hosting the tournament until at least 2034 - and most likely longer."Bitterly disappointed is an understatement," Aloisi said."We've got the country, we've got the infrastructure, we've got the people, we've hosted a great Olympics."I thought everything was positive for us and we had a massive chance of getting it."Now we have to look at winning a World Cup before we host one, because we won't be hosting one for a while."
