Wolves boss Julen Lopetegui is eager for an opening win against Carabao Cup opponents Gillingham.
Lopetegui replaced the sacked Bruno Lage in November and has led his non-World Cup stars through a series of friendly matches against Birmingham and in Spain.
And he told his first press conference as Wolves boss: 'I think they are working very hard, focused, concentrating, trying to understand what we want to do.
"In the matches against Birmingham and in Spain against Empoli and Cadiz, step by step, I think they are understanding more about us, and in the same way us about them.
"We have to improve more in the next matches and tomorrow is the first important test because it's the first official match."
