Mikel Arteta promised that it would be a “consequence” if he discovered the source of the leak, which saw that the swimming range between David Luiz and Dani Ceballos had become publicly known.
Although the Arsenal boss played a makeover after the match in training during the international break, he was obviously angry that the news of the incident left the London base in Colney.
Reports suggested that Louise and Ceballos were involved in a physical exchange after a tough fight of the latter before the end of the match in training.
It was also claimed that Louise took blood from Ceballos during the exchange, but Arteta said that the incident was not similar to any other disagreement on the training ground.
However, the Spaniard was dissatisfied that the incident leaked and when asked if it harms the club and the ethos he is trying to build, Arteta replied: “I don’t like the fact that this incident is coming out at all.
“And I will find out where it comes from and if that is the case, it is completely contrary to what I expect from each other, the privacy and confidentiality that we need and there will be consequences.”
Earlier, Arteta suggested that the couple quickly moved on from the change.
Asked what happened to Louise and Ceballos, Arteta replied: “Nothing.
“Training is very competitive, and problems happen many times. Those things are solved immediately in the team and there is not much to say.
“No problem at all (between two players).”
After the story broke on Thursday night, Ceballos took to Twitter to deny the claims – he simply retweeted the article below the words: “FAKE”.
It is not the first time that the Spanish national team player, on a seasonal loan from Real Madrid, was involved in a remake with a teammate.
The camera caught him disagreeing with Eddie Nketiah, while the two substitutes warmed up ahead of Arsenal’s victory in Fulham on the opening day of the Premier League season.
Arteta may have wanted to dismiss any talk of harmful changes at the landfill, but admitted that another incident during the international break required his attention.
Brazilian striker Villiano’s trip to Dubai came to light after a photo of the 32-year-old appeared on Instagram.
Again, Arteta will not be drawn into the debate for long, but – with current coronavirus guidelines restricting all international travel “except in limited circumstances” – the artillery chief stressed that he had spoken to Willian.
“I do not confirm anything, only that the issue has been resolved, explained and we are moving on,” he said.
“Whatever happens internally with any problems or things we don’t expect, we will always try them internally. That has been resolved and explained and we are moving on. “
Arteta would not confirm whether Willian will be in the squad for a week-long trip to the Premier League in Leeds, but he emphasized that there are other factors to count on.
“We had a conversation and I explained what I expect,” Arteta added.
“At this moment, there are a lot of personal factors, and we also have to be in their place.
“Many players have different problems, like any public figure out there, and sometimes they make decisions based on needs or the moment or what people expect from there.
“Whether they are right or not, it is obvious that we need to talk about it. But, again, it has been resolved in the right way and we are moving on.”
Arteta also saw that captain Pierre-Emerick Aubameyang must spend the night sleeping on the floor of the airport after the Gabonese team had problems entering the Gambia before qualifying for the African Cup of Nations.
Arteta will not welcome additional headaches, as both Mohamed Elneni and Sead Kolasinac tested positive for Covid-19 during the hectic international break.
Arteta will also not be able to invoke the signing deadline for Thomas Partei on Elland Road, with the Ghana midfielder missing due to a thigh injury suffered during the 3-0 home defeat by Aston Villa.
