Spain star Iniesta concerned about Brazil heat

Barcelona and Spain international midfielder Andres Iniesta has warned rival international opponents that players should not under estimate the temperature in Brazil this summer.

Iniesta, who was one of the stars of the last World Cup tournament, is concerned that the heat will prove too much for many.

"It’s going to be challenging conditions in Brazil and that’s something we learned at the Confederations Cup last year," Iniesta quipped.

"Out there, when you’re exercising hard for a long while, and sweating a lot, it is so important to rehydrate and take plenty of liquid on board."
