Midfielder John Obi Mikel says Chelsea must fight as a team to get themselves out of their current slump in form.
The Blues were dumped out of the UEFA Champions League last week by Inter Milan and slipped up in the race for the Premier League title against Blackburn at the weekend.
Carlo Ancelotti's men could only manage a 1-1 draw at Ewood Park, leaving them four points behind leaders Manchester United with a game in hand.
The defeat to Inter prompted billionaire owner Roman Abramovich to address the squad at the club's training ground last Wednesday.
When asked if the players are now playing for their future, Mikel said: "I think if we keep going like this then it is down to that. But we have to fight as a team, not as individuals.
"The owner just came to show support. We still have the Double to win and that's what he came to assure us.
"He's a football fan and understands but at the same time he wants us to put things right.
"Everyone was shattered after losing to Inter, which is why he came over - to tell us to keep going. All we can do now is look forward to Wednesday and, hopefully, put things right.
"I think the belief, mentality and everything is still there. In football sometimes you have a bad spell and we are having ours right now. We made the mistakes so we have to repair it.
"We played a very good game in the first half yesterday but in the second we didn't fight well enough."
Chelsea have the opportunity to right the wrongs of the last week when they take on Portsmouth at Fratton Park on Wednesday.
