Chris Wilder wants to see more confidence from Watford in attack after starting his time in charge of the club with defeat at QPR.
The 55-year-old was appointed head coach for the rest of the season after Slaven Bilic was sacked last week.
The 1-0 loss at Loftus Road left them 11th in the Championship, six points from the play-off places.
"We have to be a lot better in the final third with the quality we've got," Wilder said.
"There's just a little bit of fragility about us at the moment and a little bit of a lack of confidence for that final pass, run, cross, finish that gets you back into the game and go on to win it.
