The respect that Derby head coach Steve McClaren commands within football has played a major role in allowing the club to fully exploit the loan market, according to chief executive Sam Rush.
The Rams signed England Under-21 winger Thomas Ince and Manchester United's Jesse Lingard on transfer deadline day.
And Rush told BBC Radio Derby: "The key to bringing in the loan signings is Steve McClaren and his reputation.
"Clubs want their young players to come because they believe they'll develop."
Derby are second in the Championship, level on points with Bournemouth, after losing in last year's play-off final.
In both seasons, former England coach McClaren has made full use of the loan market.
"It is a very attractive base for talented young players," Rush said.
"If young players are not able to get that pathway initially in the parent club's first team, then the next best thing is to come to Derby County and be coached, play in front of 30,000 every week, train with great facilities and work with great young players."
Rush said the club were thrilled with their transfer activity in January, even if the last-minute nature of the deals for Ince and Lingard was far from ideal.
"It certainly wasn't how we would have planned it," Rush added. "We like to get our business done in good time, but a lot of it was out of our hands.
"In the last few hours I wasn't sure whether we would do no deals, one deal or two deals. But we are absolutely delighted we got two and they are top-quality additions.
"You look collectively and say 'is the squad stronger than it was on 1 January?' I would argue that it is."

He continued: "We have done some good housekeeping, giving some players the opportunity to get out and play as well.
"It has been a hugely positive month. I don't think any right-minded person could possibly suggest there is any issue with the ambition at Derby. We have identified the talent, and recruited that talent."
And Rush believes everything is now in place to secure promotion to the Premier League, thanks to a large fan base, "significant corporate and commercial support" and a "very supportive and stable ownership group".
He said: "We have backing in any number of areas and you need that.
"Steve has a good group and he hasn't suggested there is any more business he would like to do. There is probably an understanding now that this is the group.
"We have 18 league games left and I am looking forward to watching this team continue to develop with the new signings, on top of what was already a very good group of players."
