Swansea City coach Garry Monk has warned Cardiff City counterpart Ole Gunnar Solskjaer to pay more attention to the conduct of his own men.
Solskjaer accused Swansea midfielder Jonathan de Guzman of overreacting after being struck by Craig Bellamy in an incident during the south Wales derby that later earned the Cardiff forward a three-match ban.
Monk did not take kindly to those comments and escalated the row on Thursday by claiming that Kim Bo-Kyung was guilty of headbutting and punching Wayne Routledge during the same match.
"I saw Ole answering a question that my man Jon de Guzman made a meal of it," Monk told reporters.
"When you receive an elbow in the back of the head and you go down normally, I don't see how that's an overreaction.
"I would have more concerns about the 35th-minute corner for them when one of my players, Wayne Routledge, gets headbutted and punched in the face by Kim.
"If anything I would be more concerned about something like that than saying one of my players was play-acting.
"If you look at Wayne, when he gets headbutted and punched in the face, he stays on his feet. He doesn't make a meal of it.
"So I think Ole needs to look at his own players before he starts looking at mine."
Monk also revealed that striker Michu, the club's top scorer last season, will return to full training this week after ankle surgery in mid-December.
