If Kieran Tierney’s return to prominence these last few months is anything to go by, then Celtic may just have pulled off the swoop of the century in securing the services of the Parkhead favourite on a free transfer.
Fresh from making his first start in almost two years in Arsenal’s 1-1 draw against Brentford at the weekend, the full-back looks to have consigned those persistent concerns about his physical fragility to the dustbin.
You can’t help but wonder if Mikel Arteta, a man not averse to a little self-introspection, is having trouble getting to sleep at night thinking about his club’s failure to take up the option to retain Tierney’s services for another year.
