The FA have already vowed to take action following the "unacceptable" scenes which followed United's winning goal in their 3-2 triumph. Ferdinand was struck by a coin thrown from the City supporters before home goalkeeper Joe Hart stepped in to prevent the United man being confronted by a fan who came on to the pitch as order was being restored.
"If the pitch hadn't been so wet when the fan came on and he slipped over, he could have attacked Rio," Young told MUTV.
"When Wazza (Wayne Rooney) was trying to take his corner there were so many objects being thrown on to the pitch, and the one that hit Rio could have taken his eye out.
"It is not nice to see that. Hopefully that will be dealt with."
