Bolton Wanderers boss Gary Megson accepts there's a section of support he'll never win over.
"I wouldn't say they are fickle because I've had it from day one - most managers get a honeymoon period," said Megson in The Bolton News.
"Look at Sam [Allardyce]. He's not been there long, but they were 2-0 down at half-time and hadn't even come close to our goal, but there's no kind of reaction like that. I've had to cope with it for a long time. I don't like it, I think it's pathetic, and I really believe it is having an adverse effect on the team's performance.
"A lot of teams can be viewed as a few points off the top few, but also in relegation trouble - of which we're one. There are clubs who are down there who have spent £70-£90million, but are below us. I don't hear the same reaction from their fans.
"You have to wonder about the intelligence of these people - it has to be heard to be believed to be honest. As a football club and as a dressing room, we have to try to keep that negativity away from what we need to try and do.
"And will I ever win them over? No, no chance."
Megson, though, insists his record since he arrived stands up to scrutiny, adding: "I took this club further than it's ever been in Europe.
"I kept them up after having five points from 10 games, I've taken the wage bill down. I haven't spent a lot of money in doing that. I think it works out at £2.5million. Others have spent around £90million. But if your face doesn't fit, it doesn't fit. You have to accept that.
"The players, myself and my coaching staff accept it. We are as one. We have to get on with it. If people think that's helpful, that's up to them. I'm sure we can't do anything about it.
"We're having to cope with this atmosphere which is hostile and very, very difficult for everyone."
