David Moyes felt his Man United side were unlucky to go out of the FA Cup at the third-round stage against Swansea.
Scrutiny of the Scot increased as Wilfried Bony scored a late winner to earn Swansea a 2-1 win and condemn United to a fifth home defeat of the season.
With each loss comes further questioning as to whether or not Moyes is the right man to sit in Sir Alex Ferguson's seat, but he insisted his 10-man side had deserved better.
"We are a bit unlucky to lose but we probably didn't do enough to win it," Moyes, whose men are also lagging badly in the Barclays Premier League title race, told BT Sport.
"We made some opportunities, not enough, and when you're down to 10 men you want to see it out and take a replay but we didn't quite get that far."
The red Moyes referred to was the dismissal of Fabio for a studs-up challenge, which came with the game at 1-1 after Wayne Routledge and Javier Hernandez had traded goals.
"I have no issues (with the card). The referee called it right," Moyes added.
"We played quite well at times, we got near the edge of the box quite regularly but didn't make the opportunity to score a goal or when we did get an opportunity take it. That was the disappointing thing, as we went behind and came back.
"We had certain periods of good control but we didn't get a goal or create enough chances."
Moyes is currently short of attacking options and is without both Robin van Persie and Wayne Rooney.
He does not know when to expect either man back, but insists he has to keep going.
"It'll be great when we get them back, the sooner we get them back the better. They're not ready yet," he said.
"If you lose games at any club, it's difficult. At Manchester United it's even bigger, but that's the job and we get on with it."
Bony was Swansea's match-winner with a powerful near-post header.
The Ivorian now has 13 goals in his first season with the Swans and he told BT Sport: "It's good, we won, we came here not to lose and it was perfect for us. That was our wish and thank God we did it.
"I tried to do my best and if I did it today, thank you God. I am enjoying life.
"It's now important for us to take it step by step and think about the next game."
