Manchester United are sweating on the fitness of Angel di Maria and Marcos Rojo amid fears for the health and safety of Argentina's players, ahead of their exhibition friendly with Brazil in Beijing this weekend. (Sport Witness)
Aside from the usual injury fears that managers have regarding players during the international break, Louis van Gaal has something of a unique worry when it comes to those two stars.
Pollution in the Chinese capital is making conditions much more difficult for the individuals involved, and even training has been a struggle, with pictures emerging on the internet of players taking enforced breaks on the side of the field due to the smog surrounding them.
Old Trafford officials are unlikely to be pleased about Di Maria and Rojo being subjected to these conditions having already travelled halfway around the world to take part in the commercially driven glamour tie.
Red Devils fans will be keeping their fingers crossed that their fitness will not be affected, having established themselves as important part of Van Gaal's first-team squad.
