Barcelona‘s players began returning from the international break on Wednesday, with five headed straight to the treatment room with various niggles.

The biggest concern is Lionel Messi, whose hamstring strain kept him out of both of Argentina’s friendlies over the past week, although the injury is not thought to be serious.

Goalkeeper Marc-Andre Ter Stegen was kept out of Germany’s loss to Brazil on Tuesday with a knee injury although this was likely more precautionary than the result of a serious injury.

Andres Iniesta and Gerard Pique both picked up knocks in Spain’s match against Argentina, with the injury to midfielder Iniesta’s ankle slightly worrying as he has been struggling for fitness all season. Pique injured his knee in the fixture, although again, neither injury is reportedly serious.

Finally, Lucas Digne’s thigh strain, picked up during France’s game against Colombia, could keep him out for up to three weeks.
