A talented youngster, Amos was barely ten when he was playing two games a weekend while part of Crewe's academy.
"I was playing centre midfield for a local team on a Saturday, then playing for Crewe on a Sunday in goal," he tells Flashscore.
Not long after he was released by Crewe, but continued to play for his other team - Bollington United - who faced a winner-takes-all fixture to the end of their season.
"Our goalkeeper couldn't play," says Amos. "They obviously knew that I'd experience in goal and said 'Would you play?'.
Unfortunately for Amos, his parents got lost on the way to the game and could not find the pitch he was supposed to be playing on. With time running out, Amos' father remembered being given a business card by one of the other parents who had a son in the team.
"We rang the number on this window cleaning card, and they slowly directed us over the phone to where we should go," Amos says.
"We got to the pitch where they were literally kicking off any minute so I ran on and played in goal.
"I was the penalty taker that season. We won a penalty, so I went up from goal, took the penalty, ran back. We won 3-2."
Penalty scored, game won, league decided. A triumphant Amos returned to his parents.
"I just got in the car and my dad said 'Did you see the bloke with the red and white umbrella?'. I said no. He said 'That was a Man Utd scout. He wants you to go down and have a trial for a couple of weeks.'"
And so began Amos' career with Manchester United.
'All of my idols were there'
The now 35-year-old recalls a raw period in his life where he was a teenager surrounded by players he'd grown up watching, and how Edwin van der Sar helped him acclimatise in the top flight.
"He was great because I was 18 coming into the first team, I was very shy," says Amos. "All of my idols were there. He was very forthcoming and open."
While Ferguson was not quite as forthcoming, prefering instead to keep a distance from the players, Amos appreciates the influence the icon had on the start of his career.
"He gave me cup games when he felt like I deserved it," says Amos. "I always knew that I'd get an opportunity if I was doing the right things day in, day out. It was obviously amazing for me (given) the profile of every Man United game.
"Probably even more so back then. Even the preseason games were like 80,000 people there against Roma and crazy, crazy games like that."
Amos featured seven times for Manchester United, while also going out on loan to various clubs including Molde FK in Norway. Though excited about the opportunity at the time, he now says he was too young to fully appreciate the experience, given how isolating it felt to not understand the language being spoken on the training ground and beyond. His homesickness was exacerbated by the ash cloud of 2010 which prevented him going home on three separate occasions.
The shot-stopper eventually left Manchester United in 2015 after struggling for game time in the seasons that followed the departure of Ferguson - "in hindsight, when he left the club, I should have left the club" - and he joined Bolton Wanderers.
'No grey areas'
From there, his career has taken him to the likes of Millwall, Charlton and Wigan Athletic, and that experience was the reason he was snapped up by Port Vale after leaving Wigan in the summer of 2024 on the back of 83 appearances, where he provided 26 clean sheets.
Manager Darren Moore said at the time: "We made the decision to bring in a goalkeeper that possesses the quality of Ben in order to enhance the competition for the number one spot."
Port Vale would go on to gain automatic promotion at the end of last season, but now find themselves in a dogfight to survive in League One.
Four victories in their first 23 matches of the campaign has seen them languishing at the bottom of the table and five points adrift of Doncaster in 23rd, albeit with a game in hand. A recent 1-0 defeat by potential relegation rivals Peterborough, was particularly hard to take.
"The main thing we've been discussing is finding that consistency in games," Amos said. "With many games this season we've been really good in spells, but then drifted in and out the game and let teams build momentum.
"We've been on top in many games and conceded a sucker punch or missed a couple of chances ourselves.
"Which is kind of what happened at the weekend to be honest. Against Peterborough we had three big chances and then they scored in the second half off two deflections to make it 1-0."
Despite the fact their season has not gone to plan so far, Amos' time across the football pyramid means he has plenty of experience to help his team navigate these next few months - a journey he says cannot be done alone.
"There's definitely no grey areas," he says of the job he and his teammates have on their hands. "It's up to us to keep calm heads. Still have that fire in the bellies but with calm heads as well."
"We aren't going to do it ourselves, that's for sure. It's about sticking together and getting that siege mentality."
