Fulham manager Slavisa Jokanovic says mistakes are costing his side points.
The Cottagers have one win and one draw from the opening four Premier League games. They allowed Brighton to come from two goals down to pinch a point.
Jokanovic took his players that weren't involved in an international fixture to Spain over the weekend and the Serbian hopes he has ironed out some problems.
"It's not a question about individual mistakes, we need to set up better," he said.
"I really care about our positional play, if we are not in good positions mistakes arrive.
"I don't need to explain to my players when they miss passes or if they don't cross well. They need to improve these things, but I must give them a clear plan on how to play their football.
"I am not focused on individual mistakes and I am not surprised that at the beginning of the Premier League we have made mistakes but this team is new.
"I used our mini pre-season in Spain to explain to the players how we play and what we expect from our side and what is the mechanism we want to use.
"Some of these players need to know each other and have some kind of understanding of the family way of working with the team.
"Individual mistakes exist and I don't believe we will completely avoid them. In football mistakes exist but I really care about our quantity of mistakes."
