Liverpool last night twisted the knife further into a defiant Jose Mourinho's back after the Chelsea boss blamed yet another defeat on a perceived refereeing error. The 3-1 defeat at Stamford Bridge was the reigning Premier League champions' sixth loss in 11 games.

And it left Mourinho once again fuming at self-observed injustices against his side, notably referee Mark Clattenburg's decision not to show Liverpool's Lucas a second yellow card when the score was 1-1.

Two further strikes followed in Liverpool's 3-1 win which left Mourinho's side with one win in eight games and his job possibly in jeopardy. Asked if he thought the game was his last as Chelsea boss, Mourinho, who received strong backing from the home support throughout, said: "No, I don't."

Mourinho, who was subject to the first managerial vote of confidence in Roman Abramovich's 12-year ownership on October 5, will nevertheless be wary of what the future holds under an owner not noted for his tolerance. towards under-performing coaches.

Abramovich was absent from Stamford Bridge so did not witness the defeat or hear the defiant and supportive chants from the home faithful.

Mourinho hinted at his frustrations in post-match interviews, but said he could not expand on his thoughts.

The Portuguese, who is subject of two ongoing Football Association disciplinary cases, said: "I can't express my feelings in any way at all. The fight goes on, but sometimes there are fights that are very impossible to win. You go to a fight with different ammunition. There are some fights that you cannot win.

"I can play against any team, I can play against any manager. My team can play against any team and win, lose, but more than this is difficult."

Undoubtedly, though, the result will continue to raise question over the precarious status of Mourinho's future, especially after Ramires had given Chelsea a fourth-minute lead. But two fine goals from Philippe Coutinho and

Christian Benteke's late third allowed Jurgen Klopp to celebrate a second victory in his fifth game as Liverpool boss since replacing Brendan Rodgers.

Both managers berated the officials from their technical areas, the Chelsea boss treading carefully given his recent disciplinary run-ins with the Football Association.

Mourinho had the most legitimate complaint, though, when Lucas avoided a second yellow card for a challenge on Ramires with more than 20 minutes to go and the score 1-1.

Coutinho's second followed and Mourinho tried to lift his team amid chants of "You're getting sacked in the morning" from the vocal visiting support, who were able to enjoy Benteke's strike.

On the Lucas challenge, Klopp said: "If you think in England, where many situations are sometimes a little bit strange when nobody uses the whistle... in a situation like this was it a sure yellow card? I'm not sure it was a foul.

"But if you want to win at Chelsea, you need a little bit of luck. Maybe in this situation we had a little bit of luck.

"Nobody knows if they would win with 10 against 11. It's not guaranteed."

Just as he had ahead of the match, Klopp expressed sympathy for Mourinho and backed Chelsea to climb out of their predicament.

He then played down Liverpool's title aspirations. He said: "Oh please. Are you crazy? I've been here three weeks, round about. You think after one win at Chelsea we should think about this?

"We don't think about this. We have to think about the next game, about improving our game and our style. We can do much better than today."
