Javier Mascherano has jumped to boss Rafael Benitez's defence by demanding that Liverpool's stars take responsibility for the club's current crisis. The home Champions League defeat to Lyon last night has put Liverpool in grave danger of failing to qualify for the last 16.

A sixth defeat in all competitions this term also underlines the desperate run of form that has already damaged their Barclays Premier League dreams, perhaps irrevocably.

Benitez has overseen Liverpool's worst run of defeats since 1987, but midfielder Mascherano puts the blame firmly on the players.

He says: "It is easy for everyone to blame the manager and not the players.

"But the truth is that it is us out there on the pitch, the players. If we play badly it is not the manager's fault, it is ours and we must take the responsibility.

"The manager can tell us how to play but on the pitch it is down to the players. We need to keep going and to work harder.

"I do not believe that Sunday's league game with Manchester United will decide our season, but it is too early to say that. But for our confidence a win will be a massive boost.

"If we win on Sunday it will be a totally different Monday. We are not thinking about losing to United, we have done it before - twice last season - and we must do that again."

Liverpool were leading through a Yossi Benayoun first-half goal, before collapsing and conceding twice in the final 18 minutes through substitutes Maxime Gonalons and Cesar Delgado.

He added: "We always seem to make it hard for ourselves in Europe, now we have to win the last three games in the group. But we have done that before, we just have to do it again.

"We need to remember that. We can still qualify. People have said before that Liverpool are out after results like the one against Lyon, but we have hit back before and qualified, we can do it again.

"It is a must-win game now next in Lyon in a fortnight, a very important game for us.

"After the game the boss didn't talk too much, everyone was so disappointed.

"But we do need to review all the mistakes that we made, it is the players that made mistakes not the manager, so we must make sure we do not do the same things against United.

"It is a difficult situation, we have lost four in a row. But do not forget this a team who last season were doing very well, we must keep going and working.

"The team is not playing well, and a lot of players are not in the best form and we are losing confidence."

Brazilian team-mate Fabio Aurelio also believes the team, not the manager, must take the blame for Liverpool's worst run in 22 years.

He said: "We must concentrate on winning our final three games in Europe, pressure is building on us.

"But the players know that we are the only people who can change what is going wrong.

"We know what we have to do. We have to change the feeling that we are not a strong team now, especially after what we achieved last season."

Jamie Carragher has warned United he and his team-mates will give everything on Sunday.

"Beating Manchester United could be just the boost we need, we always bounce back because that us what we are about," said the vice-captain. "We've got a lot of fight and character and will want to show that against United, particularly after what happened against Lyon.

"We're going through a tough patch but we've been through them before and we'll bounce back, there's no doubt about that.

"It's always a great game against United, and that could be what we need - if we win it will give everyone a massive lift."

Teenager Martin Kelly, who made his full debut against Lyon in Glen Johnson's injury-absence, agrees.

"If we can beat United, it will give everybody a lift," he said. "I was pleased with my debut, but everyone was disappointed about the result.

"It was a cruel way to lose like that right at the end, I was off injured by then and watching on the TV and I didn't feel they were going to score again after their equaliser.

"I enjoyed the occasion even if I had to come off. But it was just one game for me, I want to be playing at this level every week. That's the aim now.

"Now we just have to look forward to Sunday's game with Manchester United and try to put things right.

"It is all about working hard as a team now to pull ourselves out of this."
