Everton boss Sean Dyche had no complaints after their 4-0 thumping at Arsenal.
Bukayo Saka, Gabriel Martinelli (2) and Martin Odegaard struck for the hosts.
Dyche later said: "[The Arsenal opener] changed the whole game. The game plan was working, which you have to do at places like this.
"Forty minutes, a goal out of nothing. I can't legislate for the second goal and the game is getting away from you. When you're 2-0 up it brings the freedom.
"They played well but couldn't break us down [for 40 minutes]. That's pleasing for us. In the second half they showed what a side they are.
"You look at Arsenal's work ethic, they knew because they came to Goodison and we put in a shift and protected our lead, they responded. The top teams learn.
"We're not naive. I knew it wasn't all rosy when I came. There's plenty of work to do, I know that.
"Every game is a big time. I've told the players that. We're not a million miles away from the previous performances.
"But we have to make the details better."
