Danny Wilson has admitted that his transfer plans are still a work in progress, as he waits to see if Lee Williamson and Kevin McDonald commit their futures to United.
"The budget remains dependent on who stays and who leaves the football club, from then we will know exactly where we stand," said the United chief.
"It is very frustrating for everyone, but it doesn't mean by the time the first ball is kicked in anger that we won't have a team capable of challenging for the holy grail of promotion.
"Every season is a challenge for different reasons; we aren't the only club making cutbacks. This isn't unusual in this industry or life in general across the world.
"It is sad we can't know what we have and be clear, but we will be up and running and ready to go come August."
The Gaffer says any genuine offers for contracted players will be considered for the good of the club, but insists his focus is on adding to his squad rather than decimating it:
"There is no pressure to sell, but if offers are made we will listen to them.
"We have got to be transparent and everyone must understand where the club is coming from in this respect, we have to make cutbacks.
"We still need to bring in players of a quality to keep Sheffield United towards the top of League One and that is what we are striving to achieve. We won't sign players for the sake of it simply to make the numbers up.
"The players who are currently out of contract across the country are having the problem of getting the wages they perhaps expect and hopefully we can pick a few up."
