Slavisa Jokanovic insisted Fulham must improve on their performance against Hull despite picking up their first home win in the Championship this season.
The Whites secured a 2-1 victory at Craven Cottage, where Stefan Johansen netted a second-half winner.
But boss Jokanovic said: “We must find the solution to play better football.
“We showed some quality but to be a more serious and competitive team we must improve.
“This is not enough. It’s not enough for me, not enough for the supporters or for the team. We must work harder and improve. We must be more solid.
“I am not satisfied with our performance, but I am satisfied with three points.”
Jokanovic added that he does not expect injured duo Tom Cairney and Rui Fonte to return for Saturday’s game against Burton.
