Boss Ruud Van Nistelrooy its Leicester's public disagreements cannot happen again.
Mads Hermansen and midfielder Boubakary Soumare argued on the pitch after Fabio Carvalho scored Brentford's final goal in Friday's 4-0 defeat to the Bees.
He said: "We have to address this type of behaviour. As a team it's good to hold each other able. But it can't be like that, out in the open.
"It was the first time it's happened. The players handled it themselves, within the team, so that was a good reaction in the dressing room.
"This week it's been assessed and it's not something that will help us going forwards. I can't see that happening again. The players know.
"I didn't think it was a huge incident but it was something we discussed. The players handled it and, for me, it's a finished matter."

I know we have injuries but 7 defensive players at home to Leicester, really? And as usual, we panic about bringing in a striker, finally get one - and whoever the manager is, refuses to start him. Baffling.

West Ham v Leicester (20:00 GMT)
Matt Piper Former Foxes winger on BBC Radio Leicester
There are ways to bridge the gap. Sean Dyche did this for six or seven years at Burnley.
If you haven't got those players that are able to bridge the gap, you have got to find them. You can look at the under-21s, the under-18s, the periphery players who aren't getting a chance.
He [Ruud an Nistelrooy] used a word that I really don't like in this situation: hope. Hope does not keep you in the Premier League. You can't keep picking the same team and crossing your fingers before you go out. It's just going to be the same as what we've seen.
There are so many untested players, or ones he has tested in the cups and then not given another opportunity.
There are youngsters who are doing incredible things. I would at least be putting some of them on the bench and bringing them on for 15 minutes. One of them could surprise you.
West Ham boss Graham Potter speaking to TNT on what he wants to see after beating Arsenal: "We played as a team. That is the foundation of it and we will need to do that again. It was a slightly different game away at the Emirates and we are at home now. We have to be the protagonists of the game and take responsibility so that is going to be a good challenge for us."
On the different challenge in facing Leicester at the bottom end of the table: "Every game is different in the Premier League. We have to take the game, we have to take the resposibility. It is a team fighting for points at the other end of the table to Arsenal. Every game in this league is really complex and competitive so we have to be good."
On a second successive start for Ollie Scarles: "He's a young player that is enthusiatic, great quality, nice temprament, good level-headed person. He wants to play for the team. He earned his place again and hopefully he can take part in a good performance and thre points again."
On addressing home struggles and trying to get three points at London Stadium: "That's the aim. We are step by step. Last game we were here we were disappointed. We have to try and put that right. Nobody gives you anything, we have to do it ourselves and perform well."

West Ham v Leicester (20:00 GMT)

West Ham defended really well against Arsenal on Saturday and countered really well.
Manager Graham Potter will be looking for his side to build on that victory, and with Jarrod Bowen up front, they will have too much firepower for the Foxes.
This is a gimme for West Ham, and it should be a routine victory for them.
I just cannot make a case for Leicester to get anything here and it looks like their hopes of staying up have had it too.
Like Southampton fans, the only thing Leicester ers have to look forward to is the chance to visit Norwich next season. It is a nice city, and I fully recommend it for a day out.

I have maintained optimism of us achieving another great escape, similar to the one we pulled off in 2014. However with our defence showing again and again that they simply aren’t good enough, and Ruud’s apparent refusal to change anything, I fear we are already down. Foxes Never Quit? I suspect the players and manager already have.
Joe, an enduring Leicester fan!
Hoping for a win for Leicester. The title is already a forgone conclusion and without a Leicester win tonight, to put pressure on Wolves, the three teams getting relegated will also soon be a forgone conclusion. So here’s to more spice and a Leicester win!
West Ham manager Graham Potter was asked about the fitness of Vladimir Coufal and Lucas Paqueta: "Both players are progressing but won't make the squad on Thursday.
"Vladi certainly has a chance for Newcastle and Lucas, we'll just have to see how he responds but certainly for Leicester no."

Interesting game tonight between West Ham and Leicester. I mean if Leicester can get a win here, then are West Ham truly safe from relegation and might Leicester still manage to avoid it?
West Ham followed up their impressive victory over Arsenal with a win against Leicester to increase the pressure on Ruud van Nistelrooy and his relegation-threatened side.
Tomas Soucek celebrated his 30th birthday with the opening goal in the first half, firing in a loose ball after Mohammed Kudus' shot was denied.
The hosts then put the game beyond the struggling Foxes just before the break when Jarrod Bowen's shot from a tight angle deflected in off Leicester defender Jannik Vestergaard, after Jamie Vardy's header from a corner had hit the woodwork for the visitors.
The Foxes, who were looking to close the gap to safety to two points with a win, had made a positive start as Wilfred Ndidi saw a second-minute effort saved.
But the Hammers' opener proved a real blow and they struggled to create pretty much anything of note after that.
The defeat leaves Van Nistelrooy's side second-bottom of the Premier League and five points from safety.
West Ham, meanwhile, are 15th, with their back-to-back wins putting them level on points with Tottenham and Manchester United, comfortably clear of trouble.
Leicester 'too ive' in West Ham defeat - Van Nistelrooy
Leicester completed one of football's fairytales when they won the Premier League in 2015-16, but the season before they produced another memorable story by avoiding relegation against the odds.
Back then they looked destined for a return to the Championship as they sat bottom of the table by April, but seven wins from their final nine games kept them up.
Their current situation is not as dire but the team, as things stand, do not look capable of pulling off an unlikely escape.
Defending has been a real problem for the Foxes this season and West Ham's two goals against them meant the visitors have now conceded 61 in 27 games, compared to 47 for the Hammers.
They should have defended both of West Ham's goals better in this game, leaving two players unmarked inside the box for the first, while Bowen was then allowed to get to the loose ball first for the second.
It is now 11 defeats from the past 12 Premier League games for Leicester, who look short of confidence and ideas - far from ideal in a relegation battle.
Hammers picking up under Potter

West Ham's Potter 'delighted' with win
Graham Potter won his first match in charge of West Ham when they beat Fulham 3-2 on 14 January, but results after that were disappointing as they lost three of their next four games.
But it is now back-to-back wins for the Hammers - with this victory following up the impressive defeat of Arsenal, which delivered a big blow to the Gunners' title hopes.
Worrying for Leicester was how comfortable West Ham were.
They controlled play for the vast majority of the game, with their confident ing in contrast to a Leicester team who looked nervous in possession.
Away from relegation trouble, unlikely to finish in the top half and out of cup competitions, West Ham will look to continue their recent mini-resurgence to ensure they finish the season in encouraging form.
