Newcastle keeping an eye on Arsenal's Tierney

Newcastle are working on their squad for next season as they are likely to face new European challenges. For this reason, they want to sign Kieran Tierney, who plays for Arsenal.
According to 'The Sun', the Scottish player would like to play at St. James' Park as Mikel Arteta is not counting on him. The Spanish coach prefers Oleksandr Zinchenko to play in that position.
However, his transfer will not be easy as Tierney has a contract with Arsenal until 2026 and Howe's side will have to pay a large sum of money if they want to sign him.
The Gunners paid 27 million euros for him but his market value has dropped due to his limited playing time at the Emirates Stadium.
