FIFA could reconsider its controversial decision to schedule some of next year's World Cup matches at midday in tropical venues, the body's president Sepp Blatter suggested on Friday in an apparent U-turn.
Blatter said FIFA has received a number of appeals to rethink its decision which has angered, among others, the world players' union FIFPro.

There will also be two 1500 kickoffs in Manaus, in the heart of the Amazon rain forest.
