David Moyes rued Sunderland's missed chances after two late goals at Old Trafford sealed a 3-1 victory for Manchester United.
Fabio Borini's 91st minute strike was far too little too late for the Black Cats, who fell behind to Daley Blind's first half goal, before conceding two inside four minutes five minutes from full time.
"I don’t believe we deserved to lose 3-1 today, but we’re at fault as we gave away two outrageous goals," Moyes told SAFSee.
"There were a couple of passes and bad decisions in the last 10 minutes of the game that made the result worse for us.
"We did very well up until then, yes we were a goal behind, but we stuck at it and we were having a go," he continued.
"Away from home we’ve not been playing that badly, with the exception of Swansea, and I thought we played well again today.
"We were playing a strong Manchester United side and we showed resilience and stuck at the task in hand.
"It’s just frustrating the mistakes that we did make and how we didn’t take any of our chances when we had them."
