Clarke, who has added defender James Clarke, midfielders Stuart Sinclair, James Hardy and Jack Kiersey and striker Elijah Adebayo to his squad, has also warned his new recruits they must realise their potential quickly if they want to avoid falling into football’s bargain basement.
Clarke, who is keen to add more strength to his squad before the season-opening clash with Northampton Town, admitted that he is always on the lookout for players he can develop with the potential to bring in good money if they can hit the heights and attract a potential new club.
Speaking via the Express & Star, Darrell said; "The signings I make will have an opportunity to kick the club on and kick themselves on.
"I say to my staff they could be million-pound players or they could be available in every good pound shop in the not too distant future.
"That is the way we are working. That is the model we are in. It is up to me and the staff to have a look at the attributes players have got and make them better players, better people.
"It’s not all about budgets. A lot of clubs get themselves in trouble, chasing a dream that is not there. We are respectful that we don’t do it that way here. We want players we can develop."
