Ipswich boss Mick McCarthy has offered a short-term contract to former West Ham midfielder Jack Collison.
Chairman Fawaz Al Hasawi has vowed to strengthen Nottingham Forest year on year, with loan arrivals possible.
A successful campaign which has delivered a spot in the Sky Bet Championship play-offs and a shot at a return to the Premier League has been aided by the performances of those drafted in on short-term agreements.
The loan market has been used to the fullest, with the likes of Patrick Bamford, George Thorne and Andre Wisdom having helped to carry Derby up the second tier standings.
Steve McClaren has been suitably impressed by all three of his leading loanees, with the trio useful assets for the present but also hot prospects for the future.
Taking that into account, discussions will be held at the end of the season regarding full-time deals.
The success of those talks will, however, rest in the hands of parent clubs Chelsea, West Bromwich Albion and Liverpool.
First team coach Paul Simpson told the Derby Telegraph: "We know what we want, it is a case of seeing what the parent clubs want to do with their players.
"These are all discussions that we need to have over the coming weeks.
"I think they (the players) have shown they can fit into our group, fit into Derby County.
"As a football club, we have shown we can look after them properly and will try and teach them the way Steve McClaren wants to play."
