Jose Mourinho doesn't believe his side are major contenders for any trophy this season.
The Portuguese made the assessment after watching his side struggle to overcome lowly Crystal Palace at Stamford Bridge.
Former Real Madrid chief Mourinho rued his side's lack of firepower and thinks this lack of a 'killer striker' will see them struggling for honours.
Mysteriously the Blues do have an in-form front man in the form of Romelu Lukaku but the big Belgian is on loan at high-flying Everton.
"I don't think we are the big contenders of any competition," Mourinho told BBC Radio 5 live.
"We don't have the striker who is going to score 30 goals in the league."
Chelsea's disappointing striking options have netted just five goals between them in the league this season.
Mourinho went on to say that this lack of killer instinct in front of goal leaves his side vulnerable to dropping points - as they have done several times this season.
"We know we don't have that striker we used to call the killer, the selfish one, the one that gives the last touch," Mourinho said.
"You don't kill and when you don't kill you are giving a chance to the opponent. It happened to us against Everton, it happened to us against Stoke. You have situations to kill and you don't, so it's difficult.
"It is a concern. We have to try to improve our defensive mistakes but I think the defensive mistakes are also a consequence of the fact you don't kill.
"When you don't kill you know you are on the edge and any mistake can lose you points. Today could finish 5-1 or 2-2 and that is hard for my heart."
The Europa League winners pursued Wayne Rooney all summer, yet Mourinho has ruled out any move for a striker in January, saying "They're not available."
