"I had a chat with Ricki and thought I could give it a go and we don't really have anyone that owns that position so I stuck my hand up and said I'd give it a bash and see how I go with it. I've been doing alright so hopefully I can make it mine."
The benefits of playing Bertos at right-back have already been evident for Herbert during the early stages of the A-League season.
Bertos has started two of their three outings - he missed their second game against the Heart due to international commitments - as the Phoenix remain unbeaten.
His move allows Herbert to make the most of his stacked midfield and use Louis Fenton and Paul Ifill on the wings with Benjamin Totori from the bench. Bertos at right-back gives the Phoenix are a more attacking team.
During the first five seasons of the Phoenix's existence, the major criticism of the side was their inability to score goals. With Bertos keen to get forward from defence, it adds another dimension to their play.
"We've got a pretty quick squad this year - a lot of young boys in there and a lot of energy - and I think we are very attacking-minded compared to previous years," Bertos said.
"Playing in that position, naturally, I go forward a lot and I like to attack because that's what I've been doing my whole career and it helps that the team attack going forward. There's nothing better than attacking. You don't want to defend the whole game, that's for sure."
The next chance the Phoenix have to showcase their new-found attacking flair will come tomorrow night when they meet top-of-the-table Adelaide United at Hindmarsh Stadium across the Tasman.
Hindmarsh hasn't been a kind venue to Wellington in previous years but, with the Phoenix's attacking philosophy and range of goal-scoring weapons in the form of Fenton, Ifill, new recruit Stein Huysegems and proven A-League performer Jeremy Brockie, they're more than a starter's chance.
The Phoenix will also welcome back skipper Andrew Durante who missed last weekend's 1-1 draw with the Brisbane Roar due to illness.
