3 more World Cup matches still to be played in the hot and humid Amazonian city of Manaus

Claudio Marchisio wasn't hallucinating. It was really, really hot at the Arena da Amazonia during the first World Cup match to be played in the Brazilian rainforest.

Marchisio and his Italian teammates were able to adapt to the steamy conditions well enough to beat England 2-1 in Group D, but both coaches complained about the heat and humidity after the game.

And there are still three more World Cup games coming to the jungle before the group stage ends.

After Saturday's match, Marchisio said "at times it felt like having hallucinations due to the heat."

The next teams that will have to deal with the conditions are Croatia and Cameroon on Wednesday. The United States will face Portugal in Manaus on June 22, and Honduras will play Switzerland on June 25.
