Kieran Tierney is "too good" not to be playing regular first-team football, former Scotland striker Kenny Miller says.
The 26-year-old international defender has been linked with a move from Arsenal to Newcastle United.
Tierney moved to London from Celtic in a £25m move in 2019 and has taken his tally of international caps to 39.
"I think he probably needs to now," former Scotland forward Miller told BBC Scotland's Sportsound.
"When he plays, he's a world class left-back. To play regular football, he probably needs to step away from Arsenal.
"There will be lots and lots of teams that will take it.
