The Whites chief executive insists the club's budget is good enough to make the top six
The Whites got their summer recruitment drive off to a promising start, adding six new faces by the middle of July.
However, they have not made any new additions since big money sale of Lewis Cook to Bournemouth, prompting suggestions his sale was used to fund the club's earlier spree.

Owner Massimo Cellino has promised season-ticket holders a partial refund if Leeds fail to make the play-offs this season, and according to Mansford all the ingredients are there for a successful campaign.
"The wage bill is high enough," the summer recruit from Barnsley told the Yorkshire Evening Post. "It’s high enough when you add in non-financial factors.
"This is Leeds United. In all but status it’s a top-10 club in this country. That will always turn people’s heads – the fact that someone on the phone is offering an opportunity at Leeds.
"Mixed with that, we’ve got one of the brightest managers of his generation (Garry Monk) who had great success playing a brand of football which had stadiums packed out in Wales. He’s got Pep (Clotet) and James Beattie with him.

"There’s the infrastructure at Thorp Arch and the fact that we average crowds of over 20,000 in the Championship. Especially under the lights at Elland Road, I don’t think there’s a more exciting place to play.
"When you factor all that in, we can recruit a team that’s competitive, definitely."
Speaking live on Radio Yorkshire this week, Mansford assured Leeds supporters the Cook money would be put towards further additions, though he admitted that some of these could be loans.
The former solicitor also said that new contracts would also be funded by deal, with discussions for Alex Mowatt and Lewie Coyle underway.

However, according to Mansford, a renewal for Whites player of the season Charlie Taylor is highly unlikely at this stage.
