The Italian's agent, Mino Raiola, revealed his anger at the decison and stated that Webb should not be able to continue refereeing.
Raiola said: "The referee saw everything, because he spoke to Mario after the action.
"So in my opinion, this referee must be banned for life because he didn't tell the truth.
"The TV images show that he is really close to the action, how can he say he didn't see it?"
Balotelli could serve a four game ban if found guilty by the FA.
