Manchester United midfielder Ander Herrera admits Huddersfield beat them on passion on Saturday.
The Terriers shocked United 2-1.
"It was a very tough day because we had a big chance to keep winning games," Herrera told MUTV. "We didn't do it. They were more aggressive in the first half and played with more passion in the first 30-35 minutes.
"After that, we came back into the game well and tried to play side to side. We put in a lot of crosses but, when you're losing 2-0 against such a passionate team, it's not easy to equal the game. But we now have to analyse why we lost. We cannot concede what we did in the first 30-35 minutes and this is the Premier League, it's not easy.
"We [just] have to analyse that between us, I don't think it's time to talk here now. We have to speak between us, but that's what happened. They were more passionate in the first 30 minutes."
