Martinelli was booked for his actions but Hackett believes the Arsenal forward should have been sent off.
He said: “Referee Sam Barrott awarded a free-kick to Arsenal, Martinelli comes rushing in and he pushes Sam out of the way.
“Now I’m sorry, Gabriel Martinelli showed total disrespect for the match official Sam Barrott in that situation.
“Although Sam issued a yellow card, for me it’s a red card. You just cannot put your hands on a referee, let alone push him out of the way.

“You’ve got to look around the country, up and down, Saturday and Sundays where we have local park referees going out and doing their games.
“What message does that send out to our local park referees?
“I thought Sam had a good game, he refereed the game well, but I think he let the refereeing community down by not sending off Gabriel Martinelli for pushing him at the award of a free-kick, so he could take the free-kick quickly.”
Will Gabriel Martinelli face retrospective action?
It is understood that Martinelli is set to avoid retrospective action from the Football Association (FA).
Due to Barrott taking action on-field, it has been widely reported that the Arsenal star will not face any further punishment by the FA.
