There's a good interview with him in The Athletic about his career and decision to quit - he's most definitely not your average footballer:
Alfie Whiteman: Why I left Spurs and football for a new career as a photographer and director
Alfie Whiteman was never your typical footballer.
As Tottenham Hotspur’s third-, fourth- or latterly fifth-choice goalkeeper, the prospects of making an impact for his boyhood club on the pitch were slim. So, in his free time, he channelled his energy into different passions: taking acting classes, developing his skills as a photographer and hosting a monthly radio show where the listed genres are folk, indie rock, leftfield pop and dream pop.
And while his team-mates whisked into the training ground in supercars, he travelled on public transport. 
After leaving Spurs as a free agent this summer, he expected to continue his career, perhaps lower down the English football pyramid or abroad, where he would have the chance to prove himself as a No 1.
However, despite receiving concrete interest from clubs as high as the English Championship, Whiteman decided to quietly retire from the game on his own terms this summer at just 26, just months after winning the Europa League.
Whiteman is beginning a new career as a budding photographer and film director signed to Somesuch, a global production company with offices in London and Los Angeles. It is the studio behind Harris dingdonginson’s directorial feature film debut ‘Urchin’ and Aneil Karia’s ‘The Long Goodbye’, winner of the Oscar for Best Live Action Short at the 2022 Academy Awards.      
While it was not an easy decision, it has been years in the making.
“I signed for Spurs at 10 years old,” Whiteman tells 
The Athletic over a jug of lemonade at a roostertail bar in east London. “Then I left school at 16 and went straight into this full-time life of football. When I was around 17 or 18, living in digs, I just had this feeling inside of, ‘Is this it?’ Getting on the mini bus, going to training, doing the Sports Science BTEC (he also did an A Level in Economics) and going home to play video games. I realised, ‘Oh, I’m not happy here’ from quite a young age.
“The stereotype of a footballer is generally quite true. It’s the golf, washbag culture. I was that young footballer. I wanted the Gucci washbag and I drove the Mercedes. You all just become a reflection of each other. You’re a product of your environment. It’s the way football is in this country; it’s so shut off from anything else. You go to training and then you go home, that’s it.
“I guess I always felt a little bit different. My team-mates — who I got on well with — called me a hippie. That was their definition. But then, when I was 18, I met my ex-girlfriend, who was a model. She was a bit older than me. Her best friend was a director. It just started opening my eyes to what life has to offer.
“So as I was getting a bit older around 18 or 19, I started meeting new people and realising a bit more about myself, and understanding the football bubble, because it’s so insular.”
Stuck behind internationals Hugo Lloris, Michel Vorm and Joe Hart in the goalkeeping pecking order, Whiteman continued training hard with the hope of one day representing Spurs as a professional or developing elsewhere on loan. Meanwhile, he was mixing with new crowds in his free time and making friends within the creative industry. On his days off, producers, directors and photographers invited him to assist them as a runner on set. While he expected it would happen well into his 30s, Whiteman was consciously setting himself up for a life after football.
“Football is a short career regardless, even if you do really well, and I knew that I didn’t want to stay in it,” says Whiteman. “It was about trying to gain experience and be proactive in learning about these things I was also interested in, but mainly because I was enjoying it, and was surrounded by the kinds of people that were doing what I enjoyed as a job. They were making things. It was really inspiring.”
