Michael Duff was disappointed to end a week of long trips with a heavy defeat for his injury struck side at Sunderland.
The Black Cats ran out 5-0 winners at the Stadium of Light in what was the third and final away fixture in the space of seven days having already visited Preston North End and Wigan Athletic and covered over a thousand miles in that time.
Duff felt his young team struggled to deal with a side no doubt destined for Championship football next season.
"We've said all along that could happen," he said. "We've had a really tough week, we've got four or five big players that aren't available, we can't carry those types of injuries when you come to these types of places.
"We looked young and naive today. The frustration is, two set plays again, we don't look like scoring a goal from a set play, so it's difficult.
"They're not in our league. We know that. If anyone expected us to come to the last two games and take points they would be optimistic. We did believe that, but we have to do more."

Attentions now turn to a return to matches at the Jonny-Rocks Stadium and a home game on Saturday against Rotherham United.
Kick-off against a side playing Championship football last term is at 3pm and tickets are available to buy online and from the ticket office.
