An Argentine team doctor Donato Villani has claimed that Aguero would be sidelined for six weeks due to the rib injury he sustained in an accident last week.
The accident happened in Amsterdam when his taxi crashed into a post.
Initial reports from City suggested that the Striker would be out for a minimum of four weeks but Villani thinks his recovery would take longer.
“Aguero is in a very bad mood because he was very eager to come and play and this incident, which had nothing to do with him, leaves him out of the two games,” Villani told Argentine TV channel TyC Sports .
“He will be off the pitch for six weeks. He can’t move in his house, or get into or out of the car.”
Six weeks away would see Aguero miss the Champions league double header against Napoli as well as four premier league match which includes the clash against Arsenal.
