The Phoenix take on the Argentine powerhouse at Westpac Stadium on July 23 in a gala-event match that promises to be one of year's most exciting sporting events.

Wellington Phoenix interim chief executive Nathan Greenham said the event was shaping up to be something special.

"Boca Juniors is one of the world's best known and most successful clubs," Greenham said.

"This is the club that has produced some of the world's greatest players - Carlos Tevez, Juan Roman Riquelme, Martin Palermo and, of course, possibly the greatest of all - Diego Maradona.

"Boca will also be bringing their first team, so fans that are at Westpac Stadium on July 23 will see the very best players this superclub has to offer against our own Wellington Phoenix."

The hosts will also field their strongest team, with the club's five All Whites - and coach Ricki Herbert - back on deck after the World Cup in South Africa.

Greenham added: "It's fantastic to think we'll have two full-strength teams in action.

"Boca will be out to light the game up with some South American style and we'll be going out to turn things on with a good win before the start of the new competition season.

"What a way for the fans to welcome back our World Cup heroes - a massive crowd for what's going to be a thrilling event."

The club's record for a gala-event match at Westpac Stadium is 31,853, set in 2007 when the Phoenix hosted David Beckham's LA Galaxy.

"It would be terrific to break that record," said Greenham.

"Given that tickets for this match are priced so well and with a club of the calibre of Boca Juniors on display there are plenty of reasons to think we could give the Galaxy record a good nudge."
