Robinson thinks video technology would have backed him.
"For me personally I have been in favour of video replays for some time now," Robinson said. "For a split second or 30 seconds or whatever it would have taken you could have sorted that out."
With Saturday's FA Cup clash finishing 2-2, the opener did not cost Spurs the match, although that was little consolation to Robinson.
"You look at it and it's not a goal," he said.
"I just cannot see how you could possibly give a goal.
"I have seen it on the TV eight or nine times and there is no one angle where you could clearly say 'yes it's in'."
