The 21-year-old admitted that he was starting to get worried about the goal drought but insisted that he is happy as along as United are winning.
He told MUTV after the game: "Before the game, I actually thought I do need a goal. Thankfully, it came today [Sunday].
"But you can't let these things play on your mind, you just play your normal game and, as long as the team keeps winning, that's the main thing."
The 21-year-old was on the receiving end of the late challenge that saw Ronald Zubar get sent off for a second yellow card and the Red's striker was in no doubt that the referee made the right decision.
"I don't think he should commit himself on the line as I wasn't really going anywhere and he dived in," said Welbeck. "It was a bit of a rash tackle. It's up to the referee to make the decision and he gave him another yellow card."
Prior to the goal against Wolves, Welbeck last scored eight weeks ago in the triumph over Arsenal.
