The result sees the Terriers relegated. They join Derby in becoming only the second Premier League team to be relegated before the end of March.
Siewert said, "I think the fans realise what we are doing. There are certain things that go wrong in a season, and we have to find all the things that we are willing to do as a club. It's great, and the supporters are part of that, and they help to bring us in the right direction.
"We are really focusing on the stuff that went wrong, and finding a better way to come back stronger."
