Brendan Rodgers believes "the weight of the jersey" is responsible for Liverpool's inconsistency this season.
After losing to Manchester City, Aston Villa and West Ham, Liverpool currently sit 11th in the Premier League table and are already seven points behind leaders Chelsea.
Liverpool spent over £100 million in the summer transfer window and Rodgers admits his new signings are still adjusting to life at Anfield and need time to settle.
“We’ve conceded eight goals and the majority of those could have been avoided but what people probably don’t get is the pressure of playing for such a big club,” said the Liverpool boss. “The weight of the jersey here is heavy for most players. Once you adapt to playing for Liverpool you become clearer in your thinking.”
Rodgers urged his players to return to form rapidly following their 3-1 defeat at Upton Park on Saturday.
“Our passing disappointed me,” said the 41-year-old. “We played more long passes than West Ham and that is something you have not seen from us in over the two years. We need to get back to doing what we do best. I look at the movement patterns in our team, our pressing in those patterns of pressure and, given the injuries, I need to retain a system for a longer period.
“The 4-4-2 diamond worked really well but it worked well with certain players and not at the weekend. Until I get all the players back that I know are multifunctional players, I’ll look at the strength of the players we do have fit. Hopefully that gives them confidence. Confidence has not been affected so far but if you don’t win games for too long it can be.”
