Maitland-Niles was involved in an unsavoury disagreement with manager Mikel Arteta over his future during the summer transfer window.
He was desperate to force a move to Everton on loan, even taking to Instagram to express his desire to be sent to a club where he would play.
"That's all in the past now," said Maitland-Niles.
"I am just thinking about the future and what's ahead of me. It was great to be out there today, getting my minutes, and hopefully there is more to come.
"Yeah [I'm] always happy to be on the pitch and play, it's a good feeling. Of course I'm looking for more minutes, I just need to keep my head down and keep going and working hard."
