Nicolas Anelka maintains Chelsea's season is very much still alive despite falling further behind in the Barclays Premier League title race.
Blues manager Luiz Felipe Scolari accepted following the comprehensive 3-0 defeat at Manchester United - watched by former boss Jose Mourinho - that his side were not playing well enough to secure silverware of any description come May.
However, Anelka, who came on as a second-half substitute at Old Trafford, insists all is not yet lost: "The fans have been frustrated by our recent results, which is logical."
He added: "As far as the players are concerned, we have not been happy with some of our games.
"The positive point is that we are still on course for the treble.
"We understand it's going to be massively tough, but everything is possible."
Scolari accepts Chelsea - with captain John Terry available again yesterday following a three-match suspension - must recapture their defensive unity.
"Losing goals at set plays is not something we accept. We train very hard to try and stop it happening," he said.
"Set-pieces have been a problem. In the first 15 or 20 games we were fantastic. I don't know why it has changed. Maybe I need to change the system because something is going wrong. It is my responsibility."
