You can take the footballer out of Scotland, but... you know the rest.
As another well-known saying goes: winter is coming. Parts of Britain endured the coldest night of autumn so far thanks to an Arctic blast.
A temperature of -9.9C was recorded overnight in Braemar, Aberdeenshire, while those waking up in London were met with closer to 4C on a bitter morning in the capital.
So, over at Arsenal's London Colney training base, it was red hats and gloves galore as Unai Emery put his squad through their paces.
All expect one man: Scotland's very own Kieran Tierney. It was a case as 'are you are' for the young defender as he trained in his summer gear.
Tierney, born on the Isle of Man, is used to an Arctic blast having spent his entire life, and career, north of the border.
Fellow full-back Hector Bellerin, on the other hand, was one of a number wearing a snood. Mesut Ozil another.
It is worth pointing out that Athens-born Konstantinos Mavropanos was opted for shorts, though seemingly sucumbed at the sight of a long-sleeve training top.
