Sam Messam, of Waikato, is bracketed to arrive late to join the squad a few weeks into the season because he is still plying his trade in Australia.
However, Robertson says former Kinetic Electrical Hawke's Bay United striker Messam "isn't 100 per cent confirmed".
On the newspaper's website, critics claim the brother of All Black Liam Messam is "just a big lump who falls over himself every time he has the ball".
"Everyone is entitled to their opinion. Mine is that Sam can come in to contribute and be a good addition to our squad, just as Miles, Ryan and Andrija were in the opening match," Robertson says.
The Blues made a clinical start on Sunday, albeit against weak opponents.
They displayed many attributes of a team that embrace the new philosophy of playing an attractive brand of football, as opposed to the one-dimensional long-ball approach often referred to as "direct" and employed predominantly in the United Kingdom.
Robertson argues his imports have come from professional backgrounds so consequently they'll bring a level of expertise that will rub off on their home-based squad.
"If there is a talent base here to fill the squad then that's great but it isn't enough," he says, adding it'll take more than home-grown talent to beat the likes of Miramar, Wellington Olympic, Western Suburbs and Wairarapa United to claim bragging rights to the league and Chatham Cup (national knockout) glory.
"It's not like we've got eight or 10 imports. We have only three."
Besides, he feels the website allegations are unsubstantiated.
"Without digging out figures, 75 per cent of our players are from Hawke's Bay.
"They are either born here or have been living here permanently," says England-born Robertson who has lived and played in the country for about a decade.
The Rovers are contemplating setting up an academy for youth players this season.
The intention is to target 16 to 19-year-olds, an age group that regional governing body Central Football doesn't cater for in its development programme. On reaching 16, players are eligible for Bay United Youth trials.
"There's nothing organised so we'll get something going this year," he says, adding age-group coach Matt Hastings will be involved, making a presentation to Central Football soon.
It concerns the elite Napier club that talent such as Harry Morton and Reilly O'Meagher gravitate to a Wellington academy, Ole, and to Mt Albert Grammar which boasts a reputable programme.
Bay United centreback/captain Robertson acknowledges other factors, such as education, may be pivotal in enticing them elsewhere but "we're trying to give them reasons to stay here to develop as footballers".
He dispels any notion the academy is there to poach talent from other Bay clubs.
The Rovers club members will have priority before others are extended the opportunity.
"We're not head-hunting players. It's for the betterment of the game," Robertson says.
Website debate also questions the work of Central Football development officer Leon Birnie, Eastern manager Phil Holt and ex-Bay United academy coach Dion Adams, who was at the helm of the Cru Bar Maycenvale United team from Hastings when they were relegated from Central League after a two-year presence when Robertson coached them to promotion.
Robertson, like Bay United coach Chris Greatholder and captain Danny Wilson, to name a few, plays for the franchise in summer and for the Rovers in winter.
The website critics, it seems, still see the two entities as one.
"I'm not sure why there's still confusion on that, to be honest," Robertson says.
