There is no more Mr Nice Guy at Nottingham Forest, according to Oliver Glasner. The Austrian has said he will change things at the club and if the players don't buy into it, they will be looking for their sixth manager in just over a year.

Forest fans booed off their team after a 2-0 loss at Brentford left them in the relegation zone for another week. They are also the Premier League's lowest scorers this season with six goals from nine games.

With Forest owner Evangelos Marinakis known as a ruthless decision-maker, that supporter anger was shared by Glasner at full-time and in an explosive press conference, the Forest head coach said:

• he has made too many compromises with this Forest team since the start of the season;
• he takes responsibility for the poor form this season, but the club are in the "same s*** situation" each year;
• Forest needs to change from top to bottom after a "pattern" of poor seasons;
• he's not at Forest to be loved, after "hugging" the players too much after defeat.

On top of that, Glasner revealed he refused a request from one of his players to make his own way back to Nottingham from London after the game, banging the table at the press conference when revealing his dismay at that request.

"We have to accept it's not good enough," said Glasner as he walked into the press conference. "If we lose four of the last five games, it's not good enough. And that's why for me, it's now time that we change things, that I change things, and that's what I will do."

Asked what he will change, he replied: "Everywhere, and I feel I could see a few things from day number one. I feel now maybe I made too many compromises in some stuff, and it's always compromises.

"It's a clear way. I will tell [the players] what we want to do, what we have to do, and if the players buy in, I think we can have a turnaround, and if not, the sixth manager [since the start of last season] will come in."

Glasner takes responsibility but points to 'pattern'

Glasner refused to blame his players for the poor start to the season and took full responsibility for the poor set of results.

But he said Forest are in a "pattern" of getting into relegation trouble in recent seasons and wants to change the club from top to bottom.

"I always take responsibility for the things I decided," said Glasner. "I decided everything. It's just one person to blame, and that's me.

"That's why I say I can't and I won't continue in the same way as Oliver Glasner. I will change things. That's so clear for me, because otherwise, again, it's the same.

"You asked the fifth manager, I think you're asking the same question [that you gave to the other four].

"I think the performances are better than the ones [the other four] have been, but it's the same. And if things won't change, you will ask the sixth [manager to come in]."

Asked if he is worried about his future, Glasner said: "I have no consequences. For me, I go home and have breakfast with my family. It's not the worst situation. Nobody needs to have pity with Oliver Glasner or with the manager.

"If I want, I could start in two weeks somewhere else. I won't do it.

"But, you know, the players, the staff, they remain in the same situation. And it's the same, sorry for the word, s*** situation that the club had last year.

"So you need to change and rebuild from the bottom to the top. And this is clear for me. And this is what I will do. And without any compromises. Zero. Zero. And if these things don't work, they will let me know [about my exit].

"I didn't come to Nottingham because I was bored at home. No, I came to Nottingham to succeed. I came to Nottingham to get the visions of the owner and the fans and the club to reality. And therefore we need to have a bigger change than maybe I thought, to be honest.

"But again, when you're in a club, then you see what's going on. And I'm desperate to get this turnaround. But again, Oliver Glasner can't do anything alone. And I said this so often, and not just after a defeat. I always said the same after winning.

"It's not me, no, we're all together and can do it. But I know where we have to go.And therefore, it's exactly this, being ruthless. And either you buy in or you leave. It's the only way.

"There is no compromise. Either you buy in where we want to go as a club. Because, and I mentioned it, if you're three times struggling, four or five Premier League seasons, struggling, being at the bottom of the league, there is a pattern. And I just know that Oliver Glasner is not here for five years."

'I'm not here to be loved by the players'

Glasner claims Forest have the players to turn their season around - but says he is no longer going to hug them after a disappointment - and that there's a more ruthless way of getting results.

"We have the personnel, but we need to get more out of the players," said Glasner. And this is where I see my responsibility.

"And again, I felt it was more [about] hugging [the players after a defeat]. But if hugging doesn't work, there's also an opposite way.

"And again, I don't need to be loved. I'm here not to be loved. I'm here to bring success to this club. And that's what I think. That's what I will change."

Asked if this could be done overnight, Glasner replied: "No. It's going to take a long time. But in this league and in your position, people will want to see changes immediately.

"Again, I think the club wanted to see changes immediately. That's why they always changed the manager. But the things didn't change.

"Again, I'm an employee. If the leadership thinks I'm the wrong one, they will let me know. But I think things won't change.

"That's just how I see it now. I think I was not harsh enough on getting a few changes."

Glasner reveals he rejected player request to travel alone

In a bid to show unity at the club, Glasner revealed he rejected a request from one of his players to travel back to Nottingham on his own from London.

Instead, the player was forced to join the rest of the squad in taking the three-hour coach.

"I was asked if a player can drive home alone. I said no," Glasner said.

"I have no understanding [why] somebody wants to go home on his own today, from London to Nottingham. No, go with the bus like everybody else. No extras. No extras.

"Buy in. Buy in every single day, every single moment, every single session. Everything we do. You buy in, you can be part of the team.

"You don't buy in? Leave. Otherwise, I'm wrong. I'm in the wrong place."

Sherwood reacts to angry Glasner

Sky Sports' Tim Sherwood:

"We're not shocked are we?

"He [Glasner] has got a history this guy. It's self-preservation, he just throws his team under the bus. And then he starts digging out about the hierarchy, that's what he is going to do.

"They're not good enough, he's right about that. He's very honest with his appraisal of his side. They are not good enough [but] he's got to get on with it. There is nothing he can do until January. He ain't going to be there in January.

"They will lose next week against Manchester City and he'll get sacked in that international break. They will be on their next manager. Look at the history of this football club, they change managers.

"Marinakis, I quite admire his stance. He gives someone an opportunity - okay people might say he does not give him long enough - but he pulled that club from where they've been to the Premier League and he's made changes along the way.

"He will not have anyone speak out against his football club. And I quite like it, he doesn't sit on his hands and wait, he just makes decisions and he will go and get another manager.

"He's probably saying: 'we spent the money, we brought some new players into the football club, some of them you knew all about and you're not getting the best out of them.'

"The buck stops with the manager and if they can't change personnel at the moment, they need to find someone who can get the best out of them and the position that they find themselves in. In the league, it's not good enough."
