Martin, 30, has cerebral palsy and is a current member of staff at Treloar's where he works as a student support assistant. Football is very much in his blood and both of his brothers are players, one of whom is Scott Sinclair who plays for Aston Villa.
Martin played in the London 2012 Paralympics. He won his first international cap in 2009 and also helped his team to win the Home Nations title and Arafura Games gold medal. This year he is set to join the National Football Museum’s Hall of Fame. The England CP star will be honoured amongst the likes of David Seaman, Denis Irwin and Rio Ferdinand.
We spoke to Martin about his passion for football.
How long have you been playing football?
Practically all my life. I started as soon as I could walk and when I was about five or six, I started to support Manchester United, so it's been a life-long obsession really.
You come from a football-mad family - did that influence you?
I got the football bug from my Dad. He used to play and was good enough to play professionally, although that didn't happen. My Mum loves it, too. She's a teacher and runs a football club at her school.
My brothers are both footballers and play professionally. Scott is 27 and plays for Aston Villa and Jake is 21 and plays for Frome Town - they're living their dream and I'm living mine. This is because my parents gave us the confidence to do what we want to do.
How did your cerebral palsy affect your attitude to sport?
I went to a mainstream school so I had to fight to keep people aware of me and show that I could do everything everyone else could do - often better. I had to try twice as hard to succeed.
Your football career nearly ended though, didn't it?
Yes, I played football at school and for mainstream teams but then I had a freak accident and broke my hip. It set me back about eight years and I was in a wheelchair for more than three years. Eventually, I had a hip replacement and now I'm back enjoying life again.
How does seven-a-side football compare with more conventional 11-a-side?
I didn't know there was a seven-a-side game of football until I got into disability sport, and it's certainly as exciting as normal football. When people find out about it, they really like it, so I'm trying to raise awareness of this game particularly to young people with disabilities.
Has Treloar's given you any support?
Treloar's was fantastic in its support, for example by giving me time off to train etc. I really feel as though I represented Treloar's as well as my country. I love all kinds of sport and I really want to help change the perception of disability sport and also encourage young disabled people to take it up.
