Herrera fractures a rib

United midfielder Ander Herrera broke a rib in the weekend game against West Ham.

The 25–year–old Spaniard, who signed in the summer, has been an important member of Van Gaal's side and becomes the 10th player in the United squad to be injured.

The club says his progress will be monitored over the next few weeks, but it is not known how long the problem will keep him out. He was substituted in the 74th minute against the Hammers after suffering the injury.
