he says there has not been a game where they have performed to capacity for 90 minutes and explains:
"Crewe was the nearest we got but there was a 15 minute wobble before the game petered out; we had a good hour at Cardiff after conceding those early goals, but I am conscious we haven't played any of the top half a dozen sides away from home."
Looking at the trip to Pride Park, he says:
"I think Derby have done well; George Burley has got them over their indifferent start and they will be quite confident.
"I saw them win up at Bradford in the week, but we have taken a lot of confidence from Wednesday.
"A lot of people will be looking to see how we cope with trips like this after the Gillingham and Rotherham games, and these matches will be the make or break of the season."
Trevor has not had much time to work with the players with there being two games a week, and says:
"I saw Gary McAllister on holiday and he said you can't believe how thick and fast the games come, but unfortunately we have a lull with a few players away coming up so we don't have them to work with us on the areas that have occurred in the recent spell.
"So it is a case of talking about things and trying to sort them out during the games."
