Wolves boss Nuno admits he has concerns about their inconsistency.
Victory against Leeds at Molineux on Friday would take them above their opponents.
Nuno said: "It's very concerning. We want to be good and consistent and work hard to achieve that.
"We are lacking a lot of the things we are trying to search for in the games.
"We have to improve some aspects of our defensive organisation, there are still a lot of mistakes which we want to avoid.
"Leeds are a very good team, unique in the way they approach the games."
