'I registered their reactions' - Forest's boss unmoved as supporters push for his ouster
Ange Postecoglou stayed resolute as Nottingham Forest fans called for his sacking after barely three weeks in control
A costly 3-2 Europa League loss to Midtjylland means the manager without a victory in his first six games in charge of Forest
He is now the first full-time manager of Nottingham Forest in a century to fail to win in any of his initial six matches
After Valdemar Byskov scored the away team's last-minute final goal at the home stadium, numerous Forest supporters shouted "You'll be fired in the morning" at the former Tottenham boss
"Supporters are disappointed. They are entitled to have an opinion on it. I listened to their opinion," said a downcast manager, who was also booed as he headed down the tunnel at full-time
"Little shocks me in soccer. It's the environment we're in. It appears that's the way things are heading. It's nothing I can influence"
Only about four months ago when Postecoglou was lifting the Europa League with Spurs, but he was dismissed over two weeks later, paying the price for a poor league season. Now he is finding it hard to achieve victories straight away at another club
The initial continental game at the stadium for nearly three decades resulted in crushing disappointment, and the accusations was pointed at the manager before the game's end had sounded
Rubbing it in, fans then sung in admiration of the former manager Nuno Espirito Santo, who is currently at West Ham
Nuno led Forest to seventh place in the top flight the previous year before being dismissed as his relationship with owner the chairman deteriorated
Defeat to the Danish opponents came after the weekend's 1-0 defeat at home to the Black Cats in the Premier League
These results have altered the atmosphere at Forest, with fans also turning to doubt the owner
"My responsibility is to ensure we get some wins for this football club and progress it," remarked the head coach
"It would be better if people were positive in their view of what I'm doing. I can only change that by winning games of football
"Regardless, that's not going to change the way I'm taking matters on. I really believe in the approach of what we're doing and I do not believe we're far away from being the team that can solve the situation we're in at the moment and achieve success"
The club invested approximately 180 million pounds in the summer, looking to build on last season's achievements, but Nuno was sacked last month after his relationship with Marinakis worsened
The Australian replaced him on 9 September, but Forest have been unable to maintain the prior season's momentum and struggled against their visitors from the Danish Superliga
The Australian head coach believes his squad are still near a breakthrough
"Yes I do, little I observed tonight alters any of that," he commented. "I understand the feeling around the place isn't going to be positive, and I understand people's attitude at the moment, especially directed at me, but it's not unfamiliar territory for me
"I believe we are on the correct path and when we get through this phase of uncertainty we are in, we will be on a positive trajectory"
Chris Wood's injury-time spot-kick failed to rescue Forest who previously let in first-half goals from one attacker and Mads Bech, around Dan Ndoye's leveler
Forest drew 2-2 at the Spanish club last week and travel to Newcastle in the league on Sunday before the pause for national teams
Postecoglou stated: "It's a really poor result from us. It was an significant evening for several factors and [a] familiar story, us failing to perform in crucial instances and facing an uphill battle
"If you allow the chance to find the net each time they get near your net, it's going to be hard to secure victories of football"
Is the manager be given time?
It is known that the owner is willing to make quick changes if he believes things are not working
At his other club, he sacked former Huddersfield coach Carlos Corberan after only less than two months as manager, while Nuno's exit came a short time after he signed a new three-year contract
Now the focus falls on the current boss
"I believe he will receive more patience because he was appointed by the chairman," former Forest and London club forward a pundit said on a sports network
"The owner will allow him additional leeway to implement his ideas in place, because at present it seems he is struggling to convey his strategies over to the players"
Ex-player and Foxes manager Martin O'Neill noted: "Wins are the key objective - it is as simple as that
"The crowd were already opposed to him in several ways, but we are a handful of matches in, you'd hardly know the name of the tea lady after that amount of duration"
On the boos, O'Neill added: "You have to deal with all the noise around you. You must not let it dictate all aspects, but you can't avoid it"
