Sevilla, Bayer Leverkusen, and Juventus were reportedly interested in Kieran Tierney before he decided to return to Scotland, joining his boyhood club Celtic. The Arsenal left-back is expected to sign a pre-contract agreement with Celtic, which will enable him to leave on a free transfer this summer since Arsenal chose not to activate a one-year extension in his contract. Having spent the previous season on loan with Real Sociedad, Tierney is now eligible to sign with clubs outside England as he enters the final six months of his Arsenal contract.
