West Bromwich Albion boss Steve Clarke says he will speak to his players if he thinks they are guilty of diving.
The Baggies felt playmaker Santi Cazorla dived to win Arsenal a penalty for the first goal in a 2-0 defeat by the Gunners on Saturday.
Clarke criticised referee Mike Jones for the decision and said: "I don't speak about players from other clubs.
"But if one of my players goes down with something similar to Cazorla, then we'll talk about it."
"I've spoken to Liam on a number of occasions this season," said Clarke. "We spoke about a number of different incidents."
