Kieran Tierney could be on the move this summer after falling out of favour at Arsenal, with former club Celtic potentially set to receive a significant sell-on fee.

The left-back has struggled to secure regular first-team opportunities this season at the Emirates, making just four Premier League starts this season.

Newcastle United are reportedly interested in acquiring the Scotland international in the upcoming transfer window, with a potential £30 million transfer fee mooted.

Celtic, who inserted a 15% sell-on clause into the £25 million deal that took Tierney to Arsenal in 2019, could potentially receive up to £4.5 million if the defender is sold for the quoted value.

Despite speculation surrounding his future, Tierney’s plans are unlikely to be decided until the end of the season.

Arsenal are focused on chasing their first Premier League title since 2003, and the left-back’s immediate future at the club remains uncertain.

However, Newcastle are keen on acquiring the defender and could make an offer in the upcoming transfer window.

Tierney’s lack of playing time at Arsenal could be a crucial factor in his decision to depart.

While he has made 25 appearances for the Gunners this season, only four have been starts under Mikel Arteta.

The arrival of Oleksandr Zinchenko has led to Tierney dropping down the order, with the Ukrainian preferred at left-back.

Despite Arteta having two back-up options in Takehiro Tomiyasu and Jakub Kiwior, the Gunners may be unwilling to sell Tierney to Newcastle if they continue to emerge as a fellow top-four contenders.
