Leigh Griffiths insists it would be "ridiculous" for any Celtic fans to want rid of Neil Lennon.
The Hoops boss and his players are under the spotlight after losing to Rangers and AC Milan before drawing 3-3 with Aberdeen on Sunday.
The draw at Pittodrie ultimately meant the Parkhead club - chasing their 10th-successive title - dropped six points behind Premiership leaders Rangers having played a game less.
Lennon believes the majority of Celtic supporters are behind him but some disgruntled Hoops fans on social media and in radio phone-ins want to see change.
Celtic striker Griffiths, speaking ahead of the Europa League clash with Lille in France tomorrow, said: "We are only two points off where we were last season at this stage.
"For people to come out and call for the manager's head is madness to be honest.
"We are still going for a treble from last season and again we qualified for the Europa League. So for them to call for his head is ridiculous.
"You are going to get pressure at a big club and just because we have had a couple of bad results doesn't mean the whole world is coming to an end.
"The most important thing is we are all together, fighting for the same cause and we go again on Thursday.
"I think the results will change, I don't think the performances have been too bad.
"There is still a long way to go in the season - we are only in October.
"There is a long way to go, a lot of games to go. Teams will drop points.
"We need to keep calm, keep focused and see each game as it comes."
Former Bhoy Charlie Mulgrew experienced all-consuming "horrible" spells when things were going badly on the pitch for Celtic.
There were times when Mulgrew did not want to leave his house because of criticism. But the Scotland international understood it was part of the job and focused on getting back to earning the adulation that comes with winning trophies.
Mulgrew believes Celtic will quickly pull through their three-game run without a victory because of the resilience that NeilLennon and his players have displayed in the past.
Previewing Sunday's Scottish Cup semi-final between his former clubs, Celtic and Aberdeen, Mulgrew said: "When you play for Celtic and Rangers, that's a major part of the job. You take the praise, you take the stick.
"It's probably the toughest place in Britain to play with the scrutiny when you lose a game, draw a game and things aren't going well. But you get praise when you are winning games and winning leagues, winning trebles.
"I have been there, it's tough. It doesn't make it any easier but it's the way it is up there.
"It's horrible but it's one you bounce back from and put it right yourself because it's part of the job.
"You've got two options: you can just buckle under or you can face it up and go into the next game and try and win it."
