Didier Drogba admits the Chelsea dressing room is not a happy place following their recent slump.
The Blues are going through one of their worst runs of form in recent history with just one win in eight league games.
And Drogba admits that the club are in the doldrums, mainly because they have never been in such a position before.
"In the last weeks Carlo Ancelotti has been unhappy - and the squad, too. Chelsea are not accustomed to defeats and the dressing room has suffered," he told The Sun.
"But the season is long and it is normal to suffer lots of changes.
"We play Wolves next and I hope our bad phase has disappeared. We need three points and that's the most important thing."
Drogba himself has been out of sorts since it was confirmed he contracted malaria late last year.
"Injuries and the malaria have damaged my performances," he continued.
"I am still not 100 per cent but I am fighting in each match to improve my playing levels and help the team.
"This season has been complicated for me by physical problems.
"It has not been easy to regain my strength but we need the points and my presence is necessary. I have always sacrificed for the team - and Chelsea need me.
"Chelsea's current position compared to last season is actually very similar but maybe our injuries and less goals have brought about a negative mood."
Chelsea's poor run has coincided with the sacking of popular coach Ray Wilkins, and Drogba admits they just had to accept the club's decision.
"Ray's exit was a decision of the club and footballers are obliged to accept it," he said.
"And although many people believe our situation is difficult Chelsea still have a chance to win the title.
"The league is very open and anything is possible.
"So emotions will run high until the end of the season - but we cannot afford any more errors. And we need to be invincible at Stamford Bridge.
"Reinforcements in January? It's always complicated. More players don't necessarily guarantee victories.
"For us now each match is a final - and we need wins."
