Michael Carrick said the boos directed at his team from the Old Trafford crowd during and after the draw with 10-man Tottenham "hurt a lot" and praised his players for coming through the experience.
United fans became exasperated with a poor start to the game midway through the first half and then booed the side off at half-time, when they were lucky not to be behind against a side who started the day bottom of the league.
Late Equaliser Sparks More Jeers
Bryan Mbeumo's goal after 72 minutes and Rodrigo Bentancur's red card looked to have handed United the victory, only for Dominic Solanke to head in an equaliser in injury time.
That led to more jeers at the end of the game and while Carrick said he understood the frustration from the fans, he said it wasn't a pleasant experience for the players.
"When things aren't quite going to plan, I understand the reaction at times. Obviously, it hurts, it hurts a lot," said Carrick. "It's not nice to go through, but sometimes you have to go through it, that's how it is.
"I care as much as anybody about this place, so sometimes you could say too much because then it overspills. But it's coming from a good place, really, and so I understand it.
"But of course, it's not nice to have to go through that. I thought the players dealt with it well, to be honest."
Manager Backs Players After Mistake
Carrick rejected the idea he was being let down by his players after an opposition team down to 10 men scored at Old Trafford for the second Premier League game in a row.
This time, Lisandro Martinez opted to engage in a physical duel with Solanke that he was never going to win, with the striker glancing Sandro Tonali's cross into the back of the net.
"No, no, I don't feel let down, because you can make mistakes," he said. "You can make mistakes, things go against you. I've made mistakes in games.
"We've all got standards, we've all got levels, the players have got levels and standards, and they know, they hold their hands up at times when something goes against them.
"It's not like everyone walks off into the distance tonight like everything's fine and it's left on me. It's not that at all. The players care, for sure, and I think you can see that even the way the game developed. When it's tough, and it was a challenging period at times in the first half, for them to work through that shows how desperate they are to then put them in that position.
"So I don't feel let down by them for making a mistake. We've just got to all help each other be better, and it's on me to help them and guide them through it."
