There are several candidates to consider.
A number of deals at the City Ground, permanent and loan, are due to come to an end in the summer of 2020.
With the focus locked on those who actually belong to the Reds, who should expect to have fresh terms put to them?
It is not difficult to argue that there are five obvious contenders.
And that is before you take matters off the field and delve head-first into the future of Sabri Lamouchi.
He has said he is happy enough in his current role, so that will do for now.
The Frenchman has also claimed that he hopes to see further movement on the signing front when it comes to those at his disposal.
Lamouchi has said in the Nottingham Post after seeing Cash and Yates commit their respective futures to the club: “We hope to continue like this with good news next week, next month, because we have a lot of good young players.”
You could start reading between the lines of the “young players” quip.
Could that be a nod towards the promise of Alex Mighten being tied down?
He is, however, already worked on terms through to 2021, so there is no real rush there.
Which means we can turn our attention back to the quintet mooted above.
On that list sits Samba Sow, Jack Robinson, Michael Dawson, Ben Watson and Sammy Ameobi.
You’d be happy to see all five back for more at the City Ground next season, wouldn’t you?
The first entries should certainly be considered a priority.
We have not seen as much of Sow lately as we would have liked, but the ability there is clear for all to see.
Having been risk averse when handing him an initial 12 months, the plan now must be to secure his services for a little longer.
Robinson is also a useful asset and has helped to counter some of the issues which have been endured in the left-back berth over recent years.
He is, of course, also capable of slotting in at centre-half.
Which is where Dawson operates.
The club captain has passed his 36th birthday and spent another spell on the sidelines this season, with any future calls probably now resting in his hands.
Does he want to play on or is a coaching career being mapped out?
Watson is also approaching the end of his playing days but, at 34 years of age, has shown that he still has plenty left in the tank.
Landing an extended stay on Trentside would complete the quite remarkable turnaround in his fortunes.
And then there is the enigma which is Ameobi.
On his day a world-beater, and on off days a pain in the proverbial.
Such mercurial talent should probably be embraced, but Forest may decide to wait a little longer before making a decision there.
Calls on all of those mentioned above may be dependent on which division the Reds appear to be heading for in 2019-20.
If a Premier League return is secured, then a clearing of the decks and lavish investment can be expected.
Should an association with the Football League be extended, then tried and tested takes on more value.
There are, however, easy claims to be made for five familiar faces to be kept around, with it intriguing to see who will be next in front of the cameras with a pen in hand.
