Sheffield Wednesday completed their busiest-ever summer transfer window last week.

The parameters Sheffield Wednesday will be working to in the winter transfer window have been confirmed following perhaps the busiest summer window in the club’s history.

Goal-getter Davis Keillor-Dunn was added to the squad in a last minute loan addition that saw the Owls ‘empty the piggy bank’ of funds available to them amid spending restrictions agreed with the EFL as part of a ‘business plan’ to exit administration. As part of that agreement, Wednesday were able to avoid a points deduction.

Some 18 senior figures joined the club over the course of the summer window, when it was made clear midway through that Wednesday were operating close to their ceiling on transfer and loan spending. The Star reported some weeks ago that this ceiling is banded across the entire season - not per window - meaning some of the savvy negotiation seen towards the end of the summer may have to be repeated again come January.

It was initially thought that Wednesday could reinvest transfer fees received into their budget as per the terms of their business plan, though this is not the case.

Speaking to BBC Sheffield as part of a media roundtable held at Middlewood Road earlier this week, Owls sporting director Simon Wilson confirmed the club would be operating broadly around the confines of loans and free transfers when the winter window comes around. Wage budgets can be increased by incoming revenues, it is understood, alongside the potential re-balancing of the existing wage commitments within the squad should the club’s decision-makers see fit.

“The restrictions give us a capacity in terms of what our total budget is and what our total budget is that can be spent on transfer fees. They're the two main elements of it,” he said.

“What counts as a transfer fee? It counts as everything, everything that's got a connection to any kind of payment with a transfer fee, so contingents and so forth all count. Now, we've had to build a squad in 60 days in spite of those, in the light of those restrictions.

“Some of those restrictions are just healthy. They're just healthy governance and what every football club would be working to. What it doesn't give us is the wiggle room that, say, a deal becomes a little bit more expensive than we planned to do or budgeted to. There's a genuine knock-on effect on the next deal with us because we can't put extra money in over the top of it where other clubs can.

“But that makes us cleaner and quicker in the deal and making sure that we get the deal done at the right numbers and gives us some hard numbers to work to. But also it makes us as a whole group evaluate the value of the players once they start to go north of the terms that we've put them in. It just sharpens us up.”

Wednesday have attracted a range of profiles in their busy summer, with youth and experience brought in alongside those of a ‘primetime’ age. Keillor-Dunn became the sixth loanee in the squad, a figure which may not entirely tally with the long-term rebuild ideal the Owls would have liked to have put in place. Longer-term contracts were signed by the likes of Louie Barry, Billy Mitchell, Jordi Liongola, Sil Swinkels and Callum Slattery, who have started brightly and could well prove to be medium or long-term additions.

“I think overall the business that we've done has been sensible and good,” Wilson said. “There have been complications, particularly with transfer fees. I think that where clubs have their best young players between 20 and 24, they're not going to be free agents and they're not going to let them out to leave for free.

“We were able to do Louie Barry because of a set of circumstances around that. But it's not ordinary that we would do that. So when our capacity for transfer fees was eliminated, it stopped our ability to go and sign that category of player.

“Those category of players are more likely to be your assets that are going to grow with the football club. So we've done more loans and one-year deals than we ordinarily would have liked to do. But as I say, I'm really, really happy with the group that we've got.”
