Everton striker Niasse became the first Premier League player banned under the new law after it was deemed he “exaggerated the effect of a normal contact to deceive the referee” against Crystal Palace on Saturday.
Conte said: “For sure we have to teach our players to be honest in every moment. I don’t like to see a simulation or dive in the box.
“When I was a player sometimes when you are losing the temptation is high to do this.
“You have to try to be honest in every game.”
