Emery once again made a decision to start both Alexandre Lacazette and Pierre-Emerick Aubameyang who both found the back of the net at the Emirates on Sunday afternoon, meaning they've now each scored in three of their last five games together.
The Englishman impressed, helping his side achieve their first clean sheet of the season in the 2-0 win.
Lacazette's sublime strike will stand the test of time, but Aubameyang's was more fortunate as the Gabon forward was clearly offside. To say 'we believe in this team, we know we have a great squad and we can go toe to toe with the big English clubs'.
Cech, 36, said Emery was bringing back the qualities required to win trophies that had gone missing under Wenger, whose last season in charge resulted in a sixth-place finish, 37 points behind champions Manchester City.
"It's a bit odd for me that the assistant could not see where Aubameyang was but we can all make mistakes".
No I like him, I thought he done well last season and today coming off the bench.
Slight risk for severe weather this Tuesday evening
Winds will be a bit breezy out of the southeast between 5 to 15 miles per hour keeping it just a little cooler near Lake Michigan. Temperatures will peak in the mid 70s but that cool front will bring back the 60s later throughout the week.
Summer signing Bernd Leno has been on the bench for all six Premier League games so far but Emery said the Germany global keeper was fine with biding his time. The game took a different start though, and it took Arsenal a while to find a rhythm. Emery later said he was about to replace Lacazette just before the France striker scored.
"Also we can give players chances to play, chances to take confidence and minutes in the game".
The 33-year-old, who offered advice to a fellow countryman as he accepted a first coaching post in England, said: "I think it's a club that can improve quite a few things".
Richarlison was lively in his return from a red card suspension, forcing Cech into a two-palmed save in the 21st minute.
Sunday's 2-0 victory at home to Everton saw Cech in top form as the Gunners recorded a fifth straight victory in all competitions.
Former Arsenal playmaker Nicholas urged Emery to stick with Aubameyang and Lacazette in his starting line up.
