McDermott feels that his team were due a break following Leonardo Ulloa's opening goal, which the 52-year-old claims was offside.
"Both sides could have won no doubt but in the Championship if you try and win and keep going, you get the breaks," PA quotes McDermott as saying. "I think we deserved a break and we got one.
"I think it connected with his hand - whether it was handball or not, I don't know.
"There was a dispute, but there was about their goal which was a yard offside. Then we get a goal with the last kick of the game and you take that on the first day of the season."
