The Saints boss was also critical of one of the linesmen on duty at Highbury.
"You've got to understand that there's plenty of history between myself and Mr Tingey," he said after the 2-0 defeat.
"Five years ago, I got sent off and he accused me of starting a fight as he had seen it clearly.
"But I took a lawyer to the Football Association hearing and there was camera footage that showed I didn't start the fight and it was impossible for him to see me. They got me instead for getting out of my technical area.
"Mr Tingey was kind of embarrassed five years ago and we've had more history since then. My players suffered because of that history, I think. Henry was three or four yards offside.
On Henry's second goal, Strachan claimed a foul should have been awarded against Ray Parlour for a foul on Danny Higginbotham.
"Ray Parlour has admitted to me that, although it wasn't intentional, he hit Danny across the face with his elbow," revealed Strachan.
"I accept that he never meant it as I know Ray Parlour but there's no question whatsoever that it was a foul.
"If you smack someone in the face with your elbow then, accident or not, it's a foul. I didn't expect Ray to get sent off, but maybe we could have got a free-kick and lobbed it in the box for a chance."
