For a guy who is used to playing games in such prodigious numbers that his former Celtic team-mate Callum McGregor once called him a freak, last season and the early weeks of this one must have been a difficult experience for Kieran Tierney.
Arsenal have evolved as a team - from soft touches to second-best - but the evolution clearly does not hold a place for the Scot anymore. To start just six Premier League games last season was a glimpse into a world he had no desire to be part of. To not feature at all in the opening league games of this season was just too much.
