Kieran Tierney is one of the tougher, more stoic players at Arsenal.
We know this because Tierney has developed a reputation for braving the cold weather at London Colney in just shorts and short-sleeved tops as of late.
That’s nothing to shout about really, but it is when every single one of your Arsenal team-mates emerges from the same building in hats, snoods and the sort of thermal gear that makes you wonder if they’re going for a hike up Everest once training finishes.
Here are some photos of the Gunners left-back during the training session yesterday evening ahead of tonight’s Europa League trip to Dundalk.


Mesut Ozil was somewhat shown up by the former Celtic defender, it must be said.
Ozil, who’s ineligible to face the Irish outfit, almost looked unrecognisable because of how he rocked up to training.
The 32-year-old sported a woolly hat and had a snood pulled up to his eyes, as he jogged behind Shkodran Mustafi.

Elsewhere, rookie goalkeeper Karl Jakob Hein was also included in Mikel Arteta’s session, prompting suggestions he could make the trip to Ireland.
The 18-year-old, who has six senior caps for Estonia, is yet to make a senior debut for Arsenal but time will tell whether Arteta takes him across the pond.
