Larne CEO Eric Perez insists he and Redball Global FC are at Larne "for the long haul".Alongside Nick Giannotti, Perez joined the Inver Reds' board of directors in July following the purchase of Kenny Bruce's 50% stake in the club.On Saturday, Larne can claim a third Irish Premiership title in four seasons should they avoid defeat at home to Dungannon Swifts which would mark the first trophy win under the stewardship of Redball.Perez has a track record in professional sports, beginning with rugby league in his native Canada where he founded professional club Toronto Wolfpack before moving across the Atlantic to work with Bradford Bulls in the Super League.He is also CEO and chairman of Truro City in English football's National League but now believes that his chance at Larne is "one of the biggest opportunities in UK sport"."It's a beautiful part of the country and a club that represents so much more than football, but a community striving for something better," Perez told BBC Sport NI's Mark Sidebottom."European ambition is another big reason we are here and being the first club from here to qualify for a European group stage, we'd like to build on that."It's been a question of taking it to the next level and that challenge is what brought me here."All-Ireland league idea poses problems A league title in his first season at the club will secure a place in next season's Champions League qualifiers and the financial benefits that come with it.Larne qualified for the group phase of last season's Uefa Conference League, while the League of Ireland's Shamrock Rovers and Shelbourne - who twice got the better of Linfield in European qualifiers - reached that stage this season.While some may feel that the idea of a combined league on the island of Ireland may work, Perez feels there is more to factor in."If you did that [all-Ireland league] you have the advantage commercially which adds to the market, but we'd lose the European places, so what do you want to prioritise - Europe or growing a bigger league?," he questioned."You'd need to bring a big broadcasting deal or sponsorship to make up for the loss of European spots."Going all-Ireland also increases expenses with travel and hotels so the budget would have to increase to be competitive with some really big clubs down there."Outspending their rivals is not the vision Perez has for Larne, but instead balancing success with sustainability.While he insists they won't live beyond their means, Perez concedes that should "the league and support grow, we will grow the budget" and having overseen the support at Truro grow significantly in his three years there, feels Larne has similar potential."We're not going to be spending big money because, just like at Truro City where we won the league with one sixth of the other teams' budget, it's about people and a chemistry which we have at Larne and that can supersede what others are paying," he stressed."We're 100% here for the long haul - I don't do short term."When we do move on, if the club is not in a substantially better place than it is now, I will have failed and I don't fail."Few expect Larne to fail in their quest to lift the Gibson Cup this weekend.Hosting a Dungannon Swifts side who may have one eye on next week's Irish Cup final suggests Gary Haveron's team hold all the aces, but football can produce the unexpected and Perez admits "the anticipation and tense feeling is palpable"."We know what we have to do, but you have to go out and get it done," he added."It's been an unbelievable season, the boys have pulled together. We were not favourite to win it this year, so what that boys have done has been unbelievable and I'm looking forward to a very exciting day on Saturday."
