Norwich City enjoyed the majority of possession in the first half, but fell to a sole Danny Welbeck goal as its winless run in the Premier League was extended to four games.
After dominating the first half, Norwich was left to rue failing to take what chances it did create as United substitute Danny Welbeck grabbed the only goal to extend the Canaries' winless run to four games.
And with other teams around them in the table also stumbling, Hughton was disappointed not to take advantage and extend the gap to the bottom three but felt Norwich had done enough to not leave empty-handed.
"It is a massive disappointment, it's certainly a game we didn't deserve to lose," Hughton told reporters. "On the balance of play, I thought we were excellent in that first half. When you're having the best period in the game – which we were in the first half – you've got to try and capitalize on it and we didn't do that.
"I thought we were good in the second half as well. It's a fortunate goal for them, but when that falls to someone of Welbeck's quality you expect them to score. Over the 90 minutes, I thought we were the better team, but of course it is goals that win games."
