There has been persistent frustration that Arsenal have been unable to get good value for money when it comes to player sales. Sporting director Edu Gaspar has come under considerable pressure from supporters to make this summer a successful one regarding both incomings and outgoings.
One name that has dominated discussions lately is Kieran Tierney. The Telegraph report that any potential fee would be upwards of £30million to secure the Scotland international's services from Arsenal.
This fee has caused something of a stir amongst the Gunners faithful however with many feeling anything less than £40m or even £50m in some cases is too small a fee for the left-back. With this is mind, football.london takes a look at the reasoning behind the valuation of Tierney and why getting as much as £40m for him would represent some excellent sales business by the club.
