Roberto Martinez wants Everton to convert a higher percentage of their chances.
The Toffees boss says he is concerned that his side have struggled in front of goal during the early weeks of the new season.
The Merseysiders have drawn all three of their games so far, finding the back of net on just two occasions.
On Saturday, they entertain Chelsea in Sky Live's early evening fixture at Goodison Park.
And the Spaniard said: "We need to realise you shouldn't need so many chances to score a goal.
"When you don't score goals, the first thing you ask is - do we create enough?
"It becomes a big problem if you haven't got the way of playing to get into the final third with a real threat.
"But that hasn't been the case - if you look at the amount of corners, good opportunities we have had.
"We are really excited and looking forward to making sure we convert those chances.
"We could easily be sitting here now with nine points. Now it is time to finish the performance off with goals."
Watch Everton v Chelsea on Sky Sports 1, kick-off at 5.30pm on Saturday.
