Players are stuck in their hotels after authorities issued an orange pollution alert - the second highest level.

They players stay inside the hotel and only go out for training. Out of every 24 hours, they spend 22 inside the hotel. Which in the build up tom what will be an intense game of football is nothing short of unacceptable.

The Argentina squad for the "Super Clasico" match at Beijing's Birds Nest stadium includes Barcelona's Lionel Messi, Manchester United's record signing Angel Di Maria and defender Marcos Rojo, and Manchester City's Martin Demichelis, Pablo Zabaleta and Sergio Aguero.
Chelsea players Willian, Oscar and Filipe Luis, Liverpool's Philippe Coutinho, Barcelona wounderkid Naymar and a KAKA making his first apperance for Brazil since 2013 are in the Brazil squad.Beijing has an ongoing problem with smog but farmers burning plant stalks after the autumn harvest has made it worse and the noxious cloud is expected to remain until Saturday.
