Since the arrival of Oleksandr Zinchenko from Manchester City last summer, Tierney has been playing second fiddle.
He has started just five Premier League games this term, including the 3-3 draw against Southampton last time out.
As a result, the Scotland international is considering his future in north London after a discussion with manager Mikel Arteta last month.
“Very good because we talked and we discussed the situation and had a very similar opinion about that,” Arteta told football.london.
“He knows his role – under me, he’s played a lot, more than any other player probably compared to the previous players at the club in the last three years and he understands the situation and he needs to challenge the situation.”
A move to Newcastle is now on the cards for Tierney, who still has three years left on his current deal at the Emirates Stadium.
Eddie Howe has fielded Dan Burn in an unnatural position at left-back this season and the acquisition of a replacement is a major priority.
Since their acquisition by the Public Investment Fund, Newcastle have been very active in the transfer market, splashing the cash on the likes of Bruno Guimaraes, Sven Botman and Alexander Isak.
They are on course to secure a return to the Champions League and will be looking to further strengthen their squad this summer to cope with the added demands of European football.
Newcastle will bid to take one step further towards continental qualification when they welcome Tottenham Hotspur to St James’ Park later today.
