The Cottagers have won just seven points so far this season, which sees them level with Norwich City but outside the bottom three courtesy of a superior goal difference.
"I am not particularly pleased [with the points total]," the Norwegian centre-back told Dagbladet. "We've got work to do - we have had a fairly tough programme, but one point on average per match is worse than we had planned.
"I hope [the win over Stoke City] was a turning point. It was a truly important win. It is still early in the season. We should not get stressed, but we are hoping to get more in the future and advance in the standings.
"I would like us to collect some points in the two upcoming matches, before the two difficult matches. It is possible to take points against United and Liverpool. We've got a tradition of taking points against the top clubs at times."
Fulham's only other victory this season was on the opening day against Sunderland.
