The Scotland international operates primarily as a left-back, but Arteta has regularly deployed him as one of three central defenders this term.
“I think Tierney has got it all, he's got a fantastic attitude," Adams said on Sky Sports' The Football Show.
“He's someone you can really work with but to play him left-side centre-half, and then sometimes playing him left back, the kid's going to get confused.
“You've got to put him in at left-back and work with him.
“I think he can be a real talent when he bombs down that left."
