Chris Porter says starting 2014 with a goal was scant consolation following the New Year's Day defeat at Walsall.
Speaking after his first-half effort at the Banks's Stadium, the powerful striker felt United's showing, especially in the opening 45 minutes, warranted more than the 2-1 defeat, which ultimately ended the eight-game unbeaten streak.
Porter said: "It was disappointing to lose the game and the unbeaten run after going in at half-time in front.
"Personally I am massively disappointed with the result, but pleased to have played well and got on the scoresheet. I am happy with my progress since Nigel came in, he has put his faith in me and I would like to think I have repaid that with my performances.
On the controversial penalty decision, the 30-year-old added: "The biggest disappointment was how the game changed in Walsall's favour on such a soft penalty call.
"Nobody in the box saw anything, their player said it was a penalty, as you would expect, but Harry was adamant it wasn't, unfortunately the key decisions sometimes go against you and prove very costly."
