Jon Brady is still looking to add to his squad ahead of Saturday’s opener against Colchester United.
“We still feel we need to add to the squad,” he said.
“We haven’t got that depth at the moment that we feel we need and we are working hard on that.
“We’ve got to make sure the players we bring in are the right fit, we’ve been patient and we have just missed out on a couple of targets. That happens and it’s a part of the game.
“We believe we’ve got up and coming talent who can be strong now and even better for the future. It’s going to take a lot of hard work but we are prepared to do that.”
