Liverpool boss Rafa Benitez says they cannot rely on Fernando Torres to win them games on his own.
Torres struggled to get out of third gear in defeat at Wigan Athletic.
"Sometimes he is the difference," said the Liverpool boss, who said the only positive to come from the game was right-back Glen Johnson's substitute appearance after more than two months out with a knee injury.
"We had two or three chances but you cannot score if you do not win the ball, or give the ball away, and if you do not win the second ball you cannot create chances.
"If we don't change what we did in the first half we will have problems but in terms of the ideas and the quality I think we have enough offensive players on the pitch."
