The full-back has described his stressful journey from Scotland to London yesterday evening as he completed a switch to Emirates Stadium
Kieran Tierney claims he was "down the park with friends" when he got the call to seal a transfer to Arsenal, with a frantic dash to the airport undertaken on deadline day.
The 22-year-old moved to the Emirates from Celtic for a £25 million ($30m) fee on Thursday afternoon, signing a five-year contract with the north London club.
The Gunners had been chasing the Scottish defender's signature throughout the summer window, with Unai Emery aiming to shore his team up at the back ahead of the 2019-20 season.
