Everton boss Sean Dyche was left upset by the manner of defeat at home to Luton.
The Hatters scored both their goals from set-pieces for their 2-1 win.
Asked about the goals conceded, Dyche said: The fact is we made them [the players] well aware like all teams do, not just us.
"Everyone has all of the analysis you could ever imagine. They are well aware of what Luton are trying to be about, and I respect that, they know it is a challenge.
"They are well aware of set pieces, well aware of the organisation, well aware of just working super hard."
