West Brom manager 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."
West Brom left-back Liam Ridgewell was accused of diving to win a spot-kick in a 4-2 win at Sunderland in November.
"I've spoken to Liam on a number of occasions this season," said Clarke. "We spoke about a number of different incidents."
The Arsenal penalty involved Baggies' right-back Steven Reid being adjudged to have caught Cazorla, although the defender insisted no contact had been made.
"No [I didn't touch him] and looking back at the replays even more so," Reid told BBC Radio 5 live.
"You'd like to think that even if there was a graze of a sock that's still not enough to go to ground. Even if it was that, which it wasn't, it's disappointing."
He added: "I might have had a little chat with Cazorla when I was waving a finger but I'm not sure I can repeat it as it wasn't too friendly.
"He almost looked a little embarrassed afterwards.
"I said to the referee there was no contact and he pretty much said that the intent was there, which I found a little bit strange."
There has been calls for the Football Association to take action over simulation, with Stoke manager Tony Pulis a strong advocate of retrospective punishment for those guilty of the offence.
Reid said: "There are always going to be one or two incidents.
"I don't believe that we should bring in any video analysis during the game. I think that would spoil the flow.
"But until something is done after a game we can carry on talking about it for as long as we like. Nothing will be done. We are always going to get incidents like that."
