Garth Crooks says Norwich should not have been allowed their winner against Newcastle.
The former player pointed to a handball in the lead up to the goal, which assisted Martin Olsson's dramatic winner.
He said: "These were three mighty points for Norwich but I must confess, I sit in the camp that insists their winning goal should never have stood.
"The ball hits Norwich midfielder Jonny Howson's hand, allowing him to control the ball sufficiently for Olsson to finish. That said, football is a game and not a science and luck should play its part in all good matches."
The goal had gone against the run of play with Newcastle fighting back from a goal down on two separate occasions.
After Aleksandar Mitrovic's second equaliser it seemed as though Newcastle were the more likely winners, before Olsson's goal for Norwich sparked wild celebrations.
The match was a big one in the battle for survival at the bottom of the table, with Newcastle now six points below the Canaries, having had a chance to draw level on points with a victory.
Newcastle do have a game in hand, but with just one point from a possible nine under Rafa Benitez, luck does not appear to be on their side as they bid to avoid relegation.
