Branislav Ivanovic admits the Chelsea squad must unite behind under-fire boss Andre Villas-Boas and help to snap the club out of their current slump.
The Blues hit a new low on Tuesday as they crashed to a 3-1 defeat at the hands of Napoli in the first leg of their UEFA Champions League last-16 encounter.
That setback on Italian soil saw the club's winless run in all competitions stretched to five games, with problems at home and abroad piling pressure on Villas-Boas and his underperforming players.
Reports of dressing room unrest have started to surface in the wake of an alarming dip in form, with senior members of the squad said to have questioned the decision-making of their coach.
Ivanovic appreciates that tough times can spark squabbles, but he believes now is the time to pull together and fight for the collective cause, rather than allow worrying cracks to spread.
"Yes. This is one of the most important moments and we all know that," said the Serbia international.
"We have to be together with each other and it can help us pass this moment."
Ivanovic added: "These things are always coming out when you're losing. What we can all do together is still believe and try to do the right things.
"I don't know what the manager is saying, but it is more about what is happening with Chelsea. That is more important than the relationship between the manager and players.
"The manager is doing his job by deciding who plays and we, as players, have to do our job. I think every player thinks like that and tries to make things better."
Ivanovic is aware of the speculation surrounding Villas-Boas and his Stamford Bridge future, but says any decisions regarding managerial matters are of little concern to the players.
"I can't say who will stay," he said.
"For us, we have to be more focused on our jobs. We don't have to care about these things. I think it's a hard position, very difficult.
"For us, it's very important to stay together. Our team, our squad is not doing what is expected of us. This is a fact."
Chelsea's success over recent years has made them unaccustomed to the struggles they are currently enduring, but Ivanovic is backing the Blues to get their campaign back on track sooner rather than later.
He added: "This is the hardest moment of my four years here. We haven't won a lot of games and our confidence is not in the best way.
"We must do all we can do to do well, we must keep going and be positive. This is the way to pass this critical period.
"If everybody works right, I think we can get a reward for our hard work."
Will Andre Villas-Boas be Chelsea manager at the start of next season?
