Carl Frampton's success is a McGuigan family affair

If Carl Frampton is crowned unified world super-bantamweight champion on Saturday, the McGuigan family can take a lot of credit.

Frampton (21-0, 14 KOs) takes on his British rival Scott Quigg (31-0-2, 23 KOs) with two world super-bantamweight titles on the line in front of a sold-out 20,000 crowd at the Manchester Arena on Saturday. Experts and fans are split 50-50 on who they think will win and tickets for the venue have also been shared equally between the boxers' supporters.

Frampton has been steered throughout his professional career by Barry McGuigan, who reigned as WBA world featherweight champion after defeating Eusebio Pedroza in 1985 until he was beaten by the desert heat and Steve Cruz in Las Vegas a year later.

McGuigan was from Clones in the Republic of Ireland but was based in Belfast for his boxing career and became a hero for both Catholic and Protestant communities in Northern Ireland during the Troubles. He was a huge celebrity in the Republic of Ireland, Northern Ireland and mainland Britain with 18 million tuning in to see his emotional win over Pedroza in front of 26,000 at Loftus Road.

IBF champion Frampton, from Belfast, has yet to enjoy the same fame as his manager and promoter, but he is one of Northern Ireland's most popular sports stars along with golfer Rory McIlroy and the national football team who have reached this summer's European Championships.

And victory over WBA champion Quigg will set up another big bout against the Cuban Guillermo Rigondeaux to decide the division's undisputed world champion. That fight, if it happens, along with other future Frampton bouts, could be on free-to-air Channel 5 or ITV in the United Kingdom, where there will be a bigger audience than Saturday's fight which is on pay-per-view television (Sky Sports Box Office).

McGuigan, 54, has had big influence on Frampton's career, but so too have his sons Shane, Jake and Blain. Shane is the trainer while Jake and Blain work on the promotional operations.

The women in the McGuigan family have also been involved: Barry's wife Sandra used to wash Frampton's clothes when he stayed at the family home in Kent earlier in his career and their daughter Nika, who is an actress, has even been involved with ticketing and public relations for some of Frampton's fights.

Barry has described Frampton as "like another son" and after he won the world title, close to the site of where the Titanic was built in Belfast, McGuigan claimed he would go on to become Ireland's best ever boxer.

There are big fights to be won before Frampton can achieve that feat but he believes his best is yet to come after refining his skills with Shane since 2010.

Shane, 28, is younger than Frampton, 29 last Sunday, but the Belfast boxer feels he has improved under the trainer at their gym in Battersea, south London.

"Shane has made me a more complete rounded fighter, it's a more professional set up," Frampton said. "He's young but he knows his stuff, he has been around boxing his whole life, and other boxers want to be trained by him now.

"I know the family so well now, they've taken me in as part of their own. Shane has grown up with boxing, he has been around boxing his whole life and he's now training others like David Haye and George Groves, and there will be more after them I'm sure.

"You think about Andre Ward and Virgil Hunter, I think guys like that have a very tight bond and relationship but I would say there are very few boxers in the world that have a relationship that I have with my manager and trainer."

Frampton describes McGuigan as an inspiration, although he has been known to ask his manager to leave the dressing room in the tense moments before fights because of his pacing up and down and nervous energy.

"Barry can inspire you to do anything," Frampton said. "He has been there and done it himself of course in boxing. His win over Pedroza was one of the most memorable fights any British boxer has been involved in.

"It's always easier taking advice from someone who has done it before and Barry has really guided me well. He took me on the pads early on in my career and his ability to fire me up is incredible.

"I was in awe of him in the beginning because he was very well known in Ireland and mainland Britain. People respect him for his boxing but also for bringing the community together. He was drilling it into me that I could be world champion early on in my career. He made me believe it."

Come fight night, Frampton will have spent 17 weeks training at his base in south London away from his wife Christine, five-year-old daughter Carla and one-year-old son Rossa. Frampton managed to return for some weekends early on in his training but has taken himself away from his family to get him ready for his toughest test yet.

"I've been away from home quite a bit and I've missed both my children's birthdays and my little boy, Rossa, just started walking so I missed all that," Frampton said. "It's not easy but these are the sacrifices I have had to make to be at this level.

"He's probably my best opponent so far. Kiko Martinez has probably been my best opponent -- he was on a good run, he was full of confidence, he'd won a world title and defended it a few times, so he was probably my best up until this one."
