Arsenal are reportedly lining up a £25m bid for Celtic defender Kieran Tierney.
Tierney, 21, has made over 160 appearances for Celtic since making his debut back in 2014.
The full-back has a long-term contract with the Hoops until the end of the 2022-23 campaign, but according to The Sun, Arsenal are determined to land him in a £25m deal in this summer's transfer window.
Tierney, who has just returned to action following a hip injury, has contributed five goals in 15 Scottish Premiership appearances for his club during the 2018-19 campaign.
The potential arrival of the Scotland international could be part of a defensive revamp at the Emirates Stadium, with the Gunners also linked with a move for Crystal Palace's Aaron Wan-Bissaka.
Unai Emery's side are currently fourth in the Premier League table, one point ahead of fifth-placed Manchester United.
