Hudson is adamant the Phoenix have got it wrong.
"Alex Rufer is one of the best young players in New Zealand," he declared following the All Whites first training session of the week which featured seven of the 23-man squad he's named to face Fiji home and away in the next eight days.
"When he played with the under-23's he was outstanding and not only was he technically good, he had fight and spirit. He made his (All Whites) debut and did really well and then got unfortunate with his injury."
"I came down to Phoenix training (recently) and he was the player I know. Reports from the other players were that he's flying in training every day. That's enough for me; I know this player, so I'm really pleased he's with us."
Hudson was also quick to point out that the job of selecting and coaching a national team that gathers infrequently and comes together from all parts of the globe is vastly different from the day-to-day management of a professional club side.
"If you look in the Premier League, there are players sat on benches who can't get in their Premier League teams, who go and play internationals and they're superstars for their countries. I can't pick Australian players or Dutch players or whatever, so my job is different to the Phoenix."
"You can't compare the way I select to the way a club selects because it's completely different," he said.
Hudson is also not averse to picking players from outside professional environments, while leaving full-time A-League players like Barbarouses, Phoenix team-mate Matthew Ridenton and Central Coast fullback Storm Roux on the outer.
"I won't be influenced by whether a player is playing for a certain team," he said.
"There are lots of young players - Sam Brotherton, Clayton Lewis, Kip Colvey, Deklan Wynne - that the Phoenix haven't signed, but that doesn't mean that other clubs (don't) value them."
"Everyone's got a different opinion on the game and players, but as the national team manager, just because they're not playing for the Phoenix doesn't mean we give them the cold shoulder. That's wrong."
The All Whites will train in the capital until Thursday before travelling to Fiji for Saturday's game in Lautoka. The return fixture is next Tuesday night at Westpac Stadium in Wellington.
