Ruben Amorim has admitted that "sometimes I want to quit, sometimes I want to be here for 20 years" and blamed his emotions for his post-match comments after Wednesday's defeat to Grimbsy.
After the Carabao Cup exit at Grimsby, Amorim said his players "spoke really loud" and that "something has to change", leading to speculation over his future.
Ahead of Saturday's visit of Burnley, the head coach admitted his emotions can sometimes get the better of him, explaining: "Sometimes I want to quit, sometimes I want to be here for 20 years.
"Sometimes I love to be with my players. Sometimes I don't want to be with my players. I need to improve on that. It is going to be hard."
Reflecting on his comments after the Grimbsy match, Amorim also said he will not change how he speaks to the media and will try to honestly reflect how he feels.
Amorim said: "I know that when I speak these things, to be really honest, every time that we have a defeat like that, I will be like that.
"Sometimes I hate my players, sometimes I love my players - this is my way of doing things. I am going to be like that. In that moment, I was so frustrated.
"You have experienced people talking about the way I should perform with the media, to be more calm. I am not going to be like that.
"I am trying to accept that and I am going to be who I am, that's why I have the passion I have. In that moment I was disappointed. We had a good pre-season and were playing better.
"That kind of performance, I was really disappointed with everything. But now it is a new game."
Friday's newspapers claimed Amorim will hold talks with United's hierarchy during the September international break over his future - with one report claiming United are fearful he could walk away from the job.
Asked about any planned talks, Amorim replied: "I always have conversations with them. I am just focused on this game [against Burnley]. I need to live this day by day. I am going to be like that all the time so prepare yourselves."
Amorim: We need Mainoo
Amorim also addressed the future of Kobbie Mainoo - who told the United hierarchy on Thursday he wants to seek a loan move away this season.
"I want Kobbie to stay and he needs to fight for his place," said the United boss. "We need Kobbie. That is not going to change.
"The players not playing with be disappointed but everyone will have opportunities. You have to fight in the week."
Asked about the future of Rasmus Hojlund, who is nearing a move to Napoli on an initial loan deal, Amorim said: "Until it is official, I cannot say much."
