Celtic have dismissed Arsenal's latest offer for Kieran Tierney due to 'too many add-ons'
Arsenal have seen a second bid of 25million rejected for Celtic left-back Tierney.
The Sun says Arsenal's offer has been turned down due to the structure of the proposed deal.
The Scottish giants are open to letting Tierney leave for the Premier League but they are holding out for 25m upfront.
Unai Emery's side are expected to make a third offer for the Scotland international as they look to wrap up his signing as soon as possible before the new season.
