Talking to the Nottingham Evening Post on Monday, Holland said "It is another season in League Two but we should be looking to get into League One, not fighting to stay up.
"We have to stop making excuses. The players who we have always said are young and learning are not that young anymore and they have played enough games now.
"I find it difficult to go out and applaud the supporters at the end of a season like this, not because they don't deserve it, but because we haven't really got anything to celebrate.
"I would rather be doing it when we are celebrating promotion or getting in the play-offs then finishing 19th.
"We desperately need to bring some new players in over the summer. We have identified people and now we just have to try to get them in."
