Weather 'too hot' for World Cup matches

The World Cup starts this summer and while there's a lot of excitement around it, there's also concerns that the hot climate will affect players.

One issue that's causing a bit of a stir is the timing of some of the matches.

But the temperature, at that time of day, can be way over 30C and some people are worried it'll be too hot for the players.
