Boxing writer Glynn Evans fills us in on 'Turbo' related trivia.
1. Terry Flanagan was born in Crumpsall Hospital, Manchester on 11thJune 1989. His father's family originally hail from Belfast, and young Terry passed many summer holidays there.
The eldest of six kids, he was raised in the city's Ancoats district. He still lives in the suburb today with his girlfriend and two year old son, Frankie.
2. The 'Turbo' first began training as a fighter aged seven, defying his parents to cross the busy Oldham Road to work out at the Ancoats Lads ABC. He later moved to the Northside ABC in Clayton, aged 14.
3. By his own estimation, Flanagan won barely half of his 60 odd amateur contests, mainly because he was disturbingly small for his age. He says: 'I always conceded weight to get fights. I'd regularly weigh in with my ball guard under my shorts and bags of coppers stuffed in my pockets and boots.'
He seldom advanced above club level but did scalp future IBF bantam boss Paul Butler in one of three contests before the pair hit their teens.
4. Since the latter end of his amateur career he has been coached by fellow Manc Steve Maylett, at the city's Finest Gym.
Steve, 32, was a former talented amateur who once scalped future two division Commonwealth king and British welterweight champion Craig Watson before an elbow injury scuppered his own ring career after just 18 bouts.
5. Aged 19, scaffolder Terry signed a pro contract with wily north-west fight face Steve Wood but initial struggled to sell tickets and his fights generally lost money. Just one of his initial 14 opponents brought a winning record as Flanagan slowly acclimatized to the profession.
6. As his reputation as a strong, skilful, awkward southpaw began to spread, Flanagan became avoided like a leper by his leading domestic rivals.
He won the English title in his 12th fight, a Prizefighter trophy in his 18th, and in gig number 20, he slaughtered ex unified world lightweight champion Nate Campbell in four rounds. However, he was still unable to secure a title shot.
7. Salvation came through Frank Warren with whom he signed a promotional deal in February 2014. In their 17 months together, the London entrepreneur has delivered tilts at the British title, WBO European belt, plus a world title eliminator.
On Saturday 'Turbo Terry' finally challenges for the vacant WBO Lightweight strap at the Velodrome in his home city after the Hall of Fame promoter secured the winning purse bid.
8. Flanagan is a huge Manchester City fan and in the past followed the Blues 'home, away and abroad.' As a kid he recalls having posters of Georgi 'Kinky' Kinkladze plastered on his bedroom wall. The City crest adorns his ring trunks.
His boxing hero as a youngster was Ricky Hatton 'but more cos he was a City fan than for his boxing!' Terry's sister Chelsea used to play for Man City Ladies but has since moved on to Preston North End.
9. If he is triumphant on Saturday - and the bookies list him as a narrow 4/5 favourite - Flanagan will become the first Mancunian to be crowned world champion since Hatton dethroned Kostya Tszyu ten years ago. He will also be the first ever Englishman to win the WBO lightweight title.
