Midfielder Karl Henry admits Wolves' players are still adjusting to the requirements of new boss Stale Solbakken.
Solbakken became Mick McCarthy's permanent replacement at Molineux after Terry Connor had been unable to prevent relegation from the Premier League.
The Norwegian's instructions had mixed results in Tuesday's pre-season friendly against Shrewsbury.
Wolves were trailing by two goals at half-time before 11 changes at the break salvaged a 2-2 draw at the Greenhous Meadow.
And Henry believes it will take time before the team can implement Solbakken's wishes on the field.
"It's going to take time for us to do exactly what the manager wants us to do," the 29-year-old former skipper told the Express and Star.
"I'm sure the boys who played in the first half won't mind me saying it wasn't a good performance.
"The boys tried to do it and I think we sat a little bit too deep.
"I think he wants us to be compact and difficult to break through, but at the same time, we can't be taking that too literally - we've got to get near the ball and press teams as well.
"He wants us to press from within our shape and we were a little bit too deep, and if you do that against any team, they're going to cause you problems.
"But it was a lot better in the second half.
"I really don't think it was personnel, but we saw what had gone wrong in the first half, and it's good for you to see as a team.
"We're still learning what he wants us to do.
"We saw what went wrong with us in the first half and we went out there with maybe a slightly different mindset.
"We got the ball up to the strikers slightly quicker and then got behind the ball in support and ended up playing a bit higher up the pitch.
"It's still early days."
