On Thursday, it was reported that Luiz and Ceballos were involved in a physical alteration following an argument after an inter-squad training match during the international break.
While it was claimed Luiz had drawn blood from Ceballos during the exchange, Arteta said the incident was not unlike any other training ground disagreement.
Asked what happened, Arteta replied: “Nothing.
“Training is very competitive and issues happen a lot of times. Those things get resolved immediately within the team and there is not much to say. There is no problem at all (between the two players).”
After the story broke on Thursday night, the on-loan Real Madrid midfielder took to Twitter to deny the claims – simply retweeting the article below the word: “FAKE”.
It is not the first time the Spain international was involved in an alteration with a team-mate.
Arteta may have been keen to brush aside any talk of a damaging altercation at the training ground but admitted another incident during the international break required his attention.
Brazil forward Willian’s trip to Dubai came to light after a photograph of the 32-year-old appeared on Instagram.
Again, Arteta would not be drawn into discussing the issue at length but – with current government COVID guidelines restricting all international travel ‘except in limited circumstances’ – the Gunners boss confirmed he had spoken to Willian.
“I don’t confirm anything, that only it is an issue that has been resolved, explained and let’s move on,” he said.
“Whatever happens internally with any issues, or things that we don’t expect, always we will try them internally. That has been dealt with and explained, and we move on.”
As well as further COVID-19 complications arising with Sead Kolasinac and Mohamed Elneny testing positive for the virus, Arteta will be unable to call upon Partey for the trip to Yorkshire this weekend.
