Liverpool assistant manager Steve Clarke has admitted that the weekend performance at West Ham was below par.
Kenny Dalglish's number two admits that the display was a surprise, but that the issues can be resolved quickly on the training ground ahead of Manchester United's weekend visit.
"If you want to be a successful team, you don't want to give too many goals away," Clarke told the official Liverpool website.
"We didn't pass the ball as well as we could and I certainly didn't think the ball retention was good enough - we allowed West Ham to pressure us a little bit.
"I think it came as a little bit of a surprise because in recent weeks we've been solid, compact and we've looked like a good team, even away from home which hasn't always been the case this season."
The former Chelsea coach is targeting a quick response to the problems though, and expects the Reds to get back to the form that helped them keep six clean sheets in seven matches before the trip to Upton Park.
"The manner in which we gave the goals away is something we can address in training and we'll look to do that this week. I'd like to be able to put it down to a one off and something that's not going to happen very often," he continued.
"We'll get down to the hard work on the training pitch, we'll put a few things right and hopefully we'll see the results at the weekend."
Clarke gave special mention to Glen Johnson and Danny Wilson during his interview with Liverpoolfc.tv, but admitted that a team effort will be needed to overcome the Red Devils on Sunday.
"We don't work with people individually, we work with the team because if you're going to defend well, you have to defend well as a whole team - it's no good picking out one or two players."
