From what I've researched about Maitland-Niles, his primary positions as a youth player were centre midfield and right midfield. When he was promoted to the first team under Wenger he was used all over the pitch at right back, left back, right wing-back, left wing-back and centre midfield. When Emery went to Arsenal, Maitland-Niles played a lot more and was either at right back or as a right wing-back so those two positions seems to have stuck as his primary positions under Arteta.
Anyway, Southampton are also reported to be interested in him so my hope that he'll sign has been hit.
