With the announcement of Forest's confirmed Europa League opponents just days away, Nuno's squad is imposing and overflowing with quality to compete once again in the Premier League.
Despite their owner, Evangelos Marinakis, plowing money into incomings this summer to stabilise their upwards trajectory, Nuno's relationship with newly-appointed Global Head of Football Edu Gaspar may have deteriorated, and still the Forest boss is calling for additions.
Although Angus Gunn was acquired following Matt Turner's permanent move away from the City Ground and Carlos Miguel departed, Nuno has been vocal about pursuing an understudy to his reliable goalkeeper, Matz Sels.
Meanwhile, full-backs Neco Williams and Ola Aina both penned new contracts at Trentside, but again, Nuno has insisted that back-ups to both are essential for him to be comfortable with setbacks or absences.
The rifts appearing in the Forest hierarchy may not bode well going forward. Yet, Nuno has been backed, and the club's personnel this season seems full of unprecedented quality all over the pitch.
Forest went on a transfer spree once the news broke that they would replace Crystal Palace in the Europa League, and before the window shuts, Nuno is calling for specific reinforcements.
Full-back targets to act as second-choice options
Forest initiated discussions with Rico Lewis over a potential move to the City Ground a few weeks ago, yet that never materialised nor progressed.
So, the Tricky Trees now have a list of candidates to bolster their defensive department.
Jose Angel Carmona emerged as a target from Sevilla, as per Fabrizio Romano.
However, the transfer guru most recently revealed talks are underway to sign Lutsharel Geertruida from RB Leipzig.
The 25-year-old Feyenoord academy product graduated to the first team of the Dutch giants and played under Arne Slot at the tail end of his time there.
The Netherlands international flourished in his homeland, and calls quickly circulated for the versatile right-back to follow Slot out the door and also to Liverpool.
Though his experiences in the Champions League helped his appeal, the jump from the Eredivisie directly into the ranks of the Premier League champions was understandably the wrong move.
He signed for German club RB Leipzig last summer, and the club finished 7th in the Bundesliga last season. He made 35 appearances in all competitions, including seven of a possible eight starts in Champions League ties.
He was deployed mainly at right-back in his games in Europe's premium competition, exactly where Nuno is seeking a backup for Aina.
Geertruida is capable at centre-back, but Jair Cunha and Morato already cater for a potential loss to Nikola Milenkovic or Murillo.
A loan with an option to buy appears to be the key to the deal, with Monday's deadline day looming.
Loans are an appropriate avenue to take for these final decisions in the market, especially given Forest's outlay this season in spite of their substantial sales.
Another prospective deal the Forest board are weighing up is left-back Victor Kristiansen from East Midlands rivals Leicester City, who were relegated from the top flight last season.
The 22-year-old amassed 30 Premier League appearances for The Foxes, sometimes pushing forward into a more advanced role.
He would be expected to cover for Neco Williams.
The Wales international sustained an injury on international duty prior to the current season while Aina missed out alongside Williams on FA Cup semi-final action against Manchester City last season.
Youngster Zach Abbott was handed his debut and recently transferred Harry Toffolo also started. Perhaps, Nuno makes a valid point about still filling in the gaps in the squad.
Whether all of the signings have been to Nuno's liking or not, he has been given resources and backed considerably. Ultimately, his role as head-coach places limits on his involvement in transfer operations, yet revealing his discontent publicly begs for questions.
Forest have the opportunity to achieve something even greater than last season, and Nuno's job seems on tenterhooks, but the project is almost at its peak on the pitch. Why waste the opportunity?
