A late tackle went unseen by referee Martin Atkinson but TV showed the extent of the vicious challenge. Because Atkinson took no action, Aguero could face a ban when the incident is reviewed.
West Ham manager Sam Allardyce revealed Noble was incensed about the tackle.
“Mark was complaining about it at half-time. It was a dangerous tackle and the referee was right in front of it.”
If the FA decide to punish Aguero, he faces a three-match suspension and if he admits the charge and the ban is imposed this week, he could miss the Manchester derby at the Etihad next Sunday.
