Qatar organizers say they are pushing ahead with plans to stage the 2022 World Cup in the summer, though they are also willing to host the tournament in the winter.
UEFA President Michel Platini has led calls to play the tournament in the cooler winter months, with FIFA general secretary Jerome Valcke saying the executive committee could move the dates on medical advice.
FIFA medical chief Michel D'Hooghe expressed concerns last week about how fans and officials would cope in the summer heat in the desert nation, which can exceed 40 degrees (102 F).
But FIFA President Sepp Blatter has said Qatar would have to request a shift to winter.
In a statement, Qatar's organizing committee said ''we are ready to host the World Cup in summer or winter. Our planning isn't affected either way.''
