Maitland-Niles was close to joining Everton on loan on Monday before Arsenal U-turned and refused to let him go.
The collapse of the move triggered the midfielder into airing his grievances on social media, where he made it clear that he wanted to move on from Arsenal on deadline day.
Arsenal informed the midfielder earlier in the morning that he will not be training with the first team anymore because of his transgression.
Maitland-Niles was still keen on forcing his way out of Arsenal today, to go to Everton, but talks between the player and Arteta seem to have calmed things down.
The Arsenal manager held clear the air talks with the 24-year-old today and made it clear that he wants him to remain part of his squad.
Arteta also provided assurances to the player that he remains part of his plans at the Emirates.
It appears the midfielder will be staying at Arsenal beyond the end of the transfer window later tonight and not joining Everton.
Maitland-Niles has two years left on his Arsenal contract and wants to play regular football this season.
