Mr Dome was confident the Auckland match would not be a repeat of the failed Beckham venture.
The lack of recognised opposition for Beckham's LA Galaxy team and the fact it followed a previous visit by Beckham to Wellington had affected that match's appeal to fans.
Underwriting the current tour was a risky exercise, but the Phoenix needed to find a way to decrease the club's financial reliance on an ownership group headed by millionaire Gareth Morgan.
"Ultimately the club has to stand on its own two feet. The owners don't have endless pockets. They are not interested in funding this [club] forever.
"There is a realisation at the club that if we are going to get to the next level we have to do something different. We needed to break the mould and do something a bit different, do something that other codes can't do which is bring world-famous clubs from overseas to this part of the world - and bring quality players that are worth millions of dollars so people can watch them play."
Tomorrow's match was being screened by Sky as a pay-per-view event, a move the Phoenix hopes will encourage more people to attend in person as well as creating an additional revenue stream.
"These [EPL] teams don't come cheap so somewhere along the line someone needs to pay," Mr Dome said.
