As well as Billy himself, the tale is told by his parents, those that knew him best growing up in the coastal town of Ardrossan in North Ayrshire, and the coaches who have helped the youngster progress from street football to the Champions League.

It has been a rapid rise for Gilmour, who made his first-team debut for the Blues just two years after moving south to London as a 16-year-old, before picking up a Champions League winner’s medal when we beat Manchester City in the final in Porto, and then following up his selection for Scotland’s Euro 2020 squad by making his international debut in a 2-2 draw with the Netherlands.

However, throughout all that, some tough love from his father and the proud welcome he always receives when returning to his hometown have ensured he keeps his feet on the ground.

‘My dad’s the first one to keep me grounded’ explains Gilmour. ‘“Constructive criticism”, he calls it. I used to hate it when I was younger. I could play well, score two goals, and he would say “yeah, you played well, but what about those two passes”. We used to fall out all the time. It’s the best way, that’s how he keeps me humble.

‘When I go back to Ardrossan, everyone knows who I am, but they don’t see me as famous because I’ve grown up with them and they’ve seen me since I was so young kicking a ball in the streets. So it’s good when I go back home, I like it.’

Despite his down-to-earth reaction to his rapid rise and determination to keep growing and achieve more in the future, it has been quite some journey for Gilmour to reach this point, and his story provides an unmissable insight into one of football’s most humble, hard-working and talented teenagers.
