Everton striker Dominic Calvert-Lewin believes they can improve in the coming weeks.
Having won two games in a row heading into the weekend, the Toffees were in good spirits.
However, a shock home loss to Luton Town has put them firmly in the relegation conversation again.
Frustrated and disappointed," Calvert-Lewin told reporters post-game.
We didn't turn today how we expected to.
We were full of confidence going into the game, but I think from the first whistle it took us too long to get into the game, and we got punished for it, switching off at set-pieces and making the game extremely difficult for ourselves to get back into.
We had chances, but we weren't clinical enough or ruthless enough in the first-half, and we should have been, myself included. And, on another day, we wanted a better result."
Then he added: It is still early in the season, and it is not panic stations; I want to make that clear. We fully expected to put in a better performance today, and we expected a better result, but it just wasn't our day.
We still have another home game next week to put it right, and we fully expect to put it right with a far, far better performance."
