Vardy was released by his boyhood club Sheffield Wednesday for being too small, but the documentary unearths footage of his blistering goalscoring form in his Stocksbridge days while also working in a factory making medical splints.

However, in the first of a series of problems in 2007, Vardy admits in the documentary he had “no stability” in his life. He had been convicted of assault when out drinking and had to wear an ankle tag for six months.

He also had a 6pm curfew which meant he had to leave matches early.

Moves to Halifax Town – where Vardy met his long‑time agent John Morris – and later Fleetwood Town followed, before his £1m move to then‑Championship club Leicester City.

Woven throughout are “The Inbetweeners” – a nickname given to Vardy’s small, all‑male social group from Sheffield – who act as his main support, alongside his wife.

“If one of us is having a problem, then get it in the group. Might get abused for a bit but at least it’s us lot keeping an eye on each other,” Vardy says.

They were needed, as former Foxes midfielder Andy King says Vardy experienced an initial “culture shock” at Leicester, where the striker admits he initially felt not good enough.

Physiotherapist Dave Rennie also corroborates accounts of Vardy’s struggles with alcohol, worsened by the pressure of the move, including “manufacturing his own Skittles vodka at home”.

Vardy would arrive at training hungover and, on one occasion, uncontactable to his then-pregnant Rebekah, or Becky as he affectionately calls her.

There was a feeling he was going to throw away his career, but the work of a “good psychologist”, the patience of manager Nigel Pearson and his own efforts to grow up after the birth of his daughter Ella kept him going.

Fame still brought further problems. A 2015 Sun on Sunday story showed him on video using a racial slur against a Japanese man in a casino.

He later described it as “a massive, massive learning curve”, explaining he was never taught which terms he could and could not use.

The film also highlights “one of the harder things” Vardy experienced when he rushed home from a team‑bonding trip to Helsinki after being told a tabloid was publishing a story about his secret biological father, who he had no prior knowledge of.

Still, Vardy became the poster boy and top scorer for Leicester’s Premier League title‑winning campaign in 2015‑16, went on to lift the FA Cup and fulfilled his agent’s prediction, made when he signed for Halifax, that he would one day play for England.

Asked whether he could have achieved more internationally after retiring from England in 2018, Vardy replied: “Possibly. We’ll never know.

“I’ll be honest, going away with England is unbelievable – you want to play for your country – but the mental side of it was tough. That changed when Gareth [Southgate] came in, but before that you were stuck in your room all day.

“You trained and then you were just back in your hotel room, pulling your hair out. There’s only so much time you can spend on a PlayStation or speaking to the kids on video calls. You’ve already not seen them and now you’re getting pulled away for another two weeks. It’s tough.

“At the time, after the World Cup, I just wanted to protect [my legs] as much as possible, prolong my club career, and as I’m still going now, it was obviously the right decision.”
