While West Coast had the highest disposal efficiency in the competition in round three - 78 per cent - Worsfold said it was the unforced nature of the side's turnovers and where they were happening that was hurting the Eagles, who fell to North Melbourne on Saturday by 25 points at Etihad Stadium.
Adam Selwood and Daniel Kerr are two senior Eagles with a kicking efficiency of roughly 50 per cent this season, and Worsfold said they needed to improve.
"We understand young players panicking and making bad decisions at times, but senior players that have been around for a long time need to be more consistent in their decision-making and ball-use," Worsfold said from Subiaco Oval on Tuesday.
"There are a couple that aren't playing at their best and we're aware of that. But they're not far off; it's not as if they're not out there trying.
"The obvious thing for us is that our bad turnovers are just handing the ball back to the opposition and it's going straight back over our head for a goal.
"Where they happen on the ground, how they happen (and) how much pressure is forcing them. We're making what looks like unforced error, or unpressured errors, in bad parts of the ground."
Worsfold said no senior players were likely to be dropped for Friday night's match with Essendon at Subiaco Oval, but the side would tinker slightly with its training routine in the lead-up to the crucial clash.
The coach also defended his highly touted young midfielders, who have come under heavy scrutiny following losses to the Brisbane Lions, Port Adelaide and North Melbourne.
"I believe in how good they're going to be," Worsfold said. "How advanced? No-one's that much of a genius to say where they are in terms of their career.
"(But) they are going to be very good players and individually if you put them into a more experienced side we would all be marveling at what they can do.
"Give them a short period of time and I think they'll start to pick up the pace of the game again and improve in those areas."
Feisty young midfielder Pat McGinnity (quad) and Mark Nicoski (shoulder) will need to pass fitness tests on Tuesday night to return against the Bombers.
Worsfold said Friday night's clash was important to restore confidence, and he understood West Coast fans' impatience after the winless start to the season.
"I'm never going to be able to say anything or show anything right now to satisfy fans, because they want wins and that's fair enough," the coach said.
"(But) as a club we want premierships and we have to build towards that and sometimes you have to wear a bit of pain.
"All I can do is say we're working very hard and we're very confident in where we're going."
