Kieran Tierney has opened up in detail about the knee injury that has left him watching on as Scotland bid to secure a spot in the World Cup finals.
The former Celtic defender missed Arsenal's English Premier League run in as the Gunners missed out on Champions League football next season to North London rivals Tottenham.
He noticed the first sign of the issue in his knee while playing against Wolves, but carried on playing for both club and country as he felt no pain.
