United meet West Brom still waiting for a first Premier League win for the season.
Wilder said, "I'm not delighted in terms of the results we have had this year.
"But I believe they have been tight games, and listening to other people's opinions, they have said the same. It doesn't ease the pain of the position we are in and it's something we are desperate to affect."
United forward Lys Mousset has been out injured this season, but Wilder says he will be involved against the Baggies.
"Lys has been a huge miss for us, he has been outstanding since his transfer last season," said Wilder.
"He is a game changer with raw pace and he is something out of the ordinary. We are looking for that in our group. One criticism is that we haven't taken big chances in big moments."
