Ange Postecoglou stayed resolute as Forest supporters called for his sacking after only a short period in charge
A damaging 3-2 Europa League defeat to the Danish side means the manager winless in his opening six games in charge of Forest
He has become the first permanent Forest manager in 100 years to not secure a win in any of his first six matches
After Valdemar Byskov scored the away team's late final goal at the home stadium, numerous Forest supporters shouted "You're getting sacked in the morning" towards the former Tottenham manager
"The fans are disappointed. They are allowed to have an opinion on it. I listened to their opinion," stated a downcast manager, who was also jeered as he headed down the tunnel at the end
"Nothing shocks me in football. It's the environment we're in. It seems that's the way things are going. It's nothing I can influence"
Only about a few months prior when Postecoglou was lifting the Europa League with Tottenham, but he was let go over two weeks later, paying the price for a dire league season. Currently he is struggling to get results right at a new team
The initial continental match at the City Ground for 29 years resulted in deep disappointment, and the accusations was directed towards the manager before the final whistle had sounded
Rubbing it in, supporters then sung in admiration of Postecoglou's predecessor Nuno Espirito Santo, who is currently at another Premier League side
The previous coach guided Nottingham Forest to seventh place in the top flight last season before being dismissed as his relationship with club owner Evangelos Marinakis deteriorated
Defeat to Midtjylland came after Saturday's 1-0 defeat at home to Sunderland in the domestic league
Such outcomes have changed the mood at the club, with supporters also turning to doubt Marinakis
"My responsibility is to ensure we secure victories for this team and progress it," said the head coach
"I would prefer if people were optimistic in their view of what I am attempting. I can only change that by winning games of soccer
"Irrespective, that's not going to affect the way I'm taking things on. I really believe in the approach of what we're doing and I don't think we're distant from being the squad that can solve the situation we're in at the moment and get the results"
The club spent around £180m in the off-season, looking to build on last season's success, but the former manager was sacked recently after his relationship with the owner deteriorated
The Australian took over from him on the ninth of September, but Forest have been unable to maintain last season's form and found it tough against their visitors from the Danish league
The Australian head coach thinks his team remain close to a turnaround
"Absolutely, little I saw tonight alters any of that," he said. "I understand the feeling around the place isn't going to be positive, and I understand supporters' stance at the moment, especially directed at me, but it's not unfamiliar territory for me
"I believe we are on the right track and when we overcome this phase of doubt we are in, we will be on a good path"
Chris Wood's injury-time penalty failed to rescue the team who earlier let in first period scores from one attacker and another player, either side of Dan Ndoye's equaliser
Forest drew 2-2 at the Spanish club recently and go to Newcastle in the Premier League on Sunday before the pause for national teams
The manager said: "It's a really poor result from us. It was an significant evening for many reasons and [a] similar tale, us failing to perform in crucial instances and facing an uphill battle
"If you allow the chance to find the net each time they approach your net, it's going to be difficult to secure victories of soccer"
It is known that the owner is not afraid to make swift changes if he feels matters are not working
At Olympiacos, he dismissed ex-Huddersfield coach a previous appointment after just less than two months as manager, while the ex-manager's exit occurred weeks after he agreed to a new three-year contract
Now the spotlight shifts to the current boss
"I believe he will get extra time because he was hired by the owner," former Forest and West Ham forward Michail Antonio said on TNT Sports
"He will give him extra time to get his philosophy in place, because at present it seems he finds it challenging to convey his strategies across to the players"
Ex-player and Foxes boss Martin O'Neill noted: "Victories are the name of the game - it is as simple as that
"The fans were already against him in many aspects, but we are a handful of matches in, it's too soon to know the identity of the tea lady after that amount of time"
On the jeers, he added: "One must handle with all the noise around you. You can't allow it dictate everything, but you cannot ignore it"
