Wolves boss Julen Lopetegui admits they need "perfection" to win today's Black Country derby against Aston Villa.
A win would just about secure Wolves Premier League safety.
Lopetegui said, It's a match against a very good team. They have improved a lot from the first half of the season until now.
They are a very good team, good players, very experienced coach. They have a very clear idea and have developed, and after they have the quality to damage you in each moment.
They have very big players so we have to have confidence in our players, our idea, to be able to beat them. We have to be very close to perfection to play against this kind of team.
Above all, we have to put the focus on our strengths, be confident with our work and we have to be ready.
I prefer to talk about us, our strengths, because we have to be confident in our energy, our strengths, and put the focus to be able to compete with them."
