The 20-year-old provides Phoenix coach Ernie Merrick with various options in the midfield and has already formed a bond with fellow Spaniard Albert Riera, who was impressive again for Wellington on Wednesday night.
"He's a nice guy and so easy to get along with," Rodriguez said of his midfield mate. "It's just the same on the pitch."
Newcastle opened this week's Football United Tour with a 4-0 victory over Sydney FC in Dunedin on Tuesday as the heavyweights flexed their muscles.
Newcastle manager Alan Pardew saw the Phoenix's tough-tackling approach on Wednesday and said he may have a word with Merrick and the officials ahead of today's game to help keep a lid on things.
"I'm sure it'll be competitive," Pardew said.
"I know there were a couple of challenges [against West Ham] that were probably not suitable for pre-season, so hopefully we don't see those."
Merrick confirmed he would likely employ most of the same starting XI that beat West Ham for today's game, which gives the uncontracted Tom Doyle another opportunity to prove he is worthy of a full-time deal after impressing at left back on Wednesday night.
All Whites midfielder Michael McGlinchey wasn't expected to be available as no ruling had emerged from his ongoing contract saga.
As part of today's double-header, West Ham play Sydney FC before the Phoenix meet Newcastle with a near sell-out crowd expected at Westpac Stadium.
Meanwhile, the Phoenix confirmed yesterday that they have signed versatile Dutch utility Roly Bonevacia on a two-year contract.
"This is exactly what we wanted," Merrick said. "We wanted a defensive player who was comfortable in the midfield, at centre back when we lose players to the All Whites and a fullback when we need him to fill in."
Bonevacia's arrival means the club has filled out their import quota for the upcoming season but Merrick said the Phoenix would find a way to accommodate the off-contract Paul Ifill when the veteran striker returns from his Achilles tendon injury.
The 34-year-old could qualify as a "local" this season given he will have lived in New Zealand for five years come September.
