Swansea boss Garry Monk said Stoke winger Victor Moses should be "ashamed of himself" and punished for his role in helping Stoke win a penalty.
Monk's team lost 2-1 at the Britannia Stadium with his defender Angel Rangel penalised for a foul on Moses.
And the Swans boss, whose team are without a win in five league games, said: "Moses should be done for diving, for cheating."
Stoke boss Mark Hughes described MoHughes said: "I actually heard him say that my player was a cheat which is unacceptable in my view.
"He's (Monk) obviously upset. We have to come in here 20 minutes after the game to speak about what's gone on and sometimes you just have to bite your tongue and maybe that will come from experience."
Swansea led through a Wilfried Bony penalty but Stoke levelled through Charlie Adam's spot kick and substitute Jonathan Walters headed home the winner after the break.nk's comments as "unacceptable".
