Neil Harris has addressed the spat between Cardiff City pair Leandro Bacuna and Callum Paterson after Nottingham Forest's 1-0 win in South Wales on Tuesday night.
The pair were seen clashing at full-time after Tiago Silva's second half winner secured a big three points for Sabri Lamouchi's side as they continue their fight for automatic promotion to the Premier League.
Tensions were high between the Paterson and Bacuna after Cardiff suffered a second straight loss in the League and a third game without a win in the League.
That has seen them drop six points from Preston North End in sixth place, the final play-off spot.
Cardiff players had to restrain the duo and even Forest striker Lewis Grabban got involved as the pair went head-to-head in a furious coming together.
And Harris has no problem with aggression and passion - as long as it is channeled in the right way.
"I spoke afterwards," Harris told WalesOnline.
"I didn't see the incident at the time. I was down the tunnel.
"But when I was asked afterwards, I was quite reflective. It is a passionate game. We are a passionate football club.
"We talk about the passionate fanbase.
"A workman-like fanbase.
"We as a club wear our heart on our sleeve - I'm all for personality and aggression at the right times.
"Having reflected on it and looked at it back.
"It reminded the players, them two in particular, but the group too - we do have a young fanbase that does attend games and that disappointment and those argumentative moments need to be dealt with in private in the changing room.
"99 out of 100 are.
"So I've reminded them of their professional responsibilities as sportsmen and how they're role models."
Harris also revealed the pair have buried the hatchet.
"As a pair, they're great," he added.
"They're really, really good guys. They were fine afterwards and I've had an apology from both of them.
"I said to them, 'it's not just about the apology, it's about making sure it doesn't happen again'. They want to win and they were disappointed afterwards.
"It's unfortunate and it's not a good look. It doesn't look great for the football club and I tried to play it down afterwards, because it's not something I want us to be remembered for.
"It doesn't reflect the group. They're not like that in the group. Yes, they want to win, but there's not a horrible mentality in the group and they've really evolved since I've been here. It was an unsavoury incident. The players have put it to bed. I've dealt with it behind the scenes.
"What I know about the group is they're really good lads. They're really good lads. What's important for everyone to know is that there's no underlying issue.
"We move on."
