However, Robertson emphasised the rest of Bueno's teammates toiled to ensure he got precious possession and other key variables - such as time, space and angles - to be the bloke who pulled the trigger with some assertiveness.
"You know, there are some big moments and passages of play to lead up to creating chances for him so he's managed that really well, I suppose."
The former Oceania League-winning Team Wellington centreback, who is now Thirsty Whale Hawke's Bay United skipper, said the hosts were effective on the counterattack which had caused the James Hoyle-captained Rovers some grief in the early stage of the game.
"We strong enough to see that out and then got our lead but in the second half it was a much more clinical performance," he said, praising his troops for frustrating Wellington United by churning out more quality ball when they were in possession.
Defender Danny Wilson and vice-captain Joshua Stevenson had struck the woodwork but it was a comprehensive performance in his overall assessment.
"The first half was more even but it was a good win for us on the road with the league table looking so tight," Robertson said.
The Declan Edge-coached Advanced Electrical Western Suburbs sit three points behind the Blues but boast a superior goal difference, which dropped to four today, but the defending champions host Miramar Rangers at Endeavour Park in a 2.30pm kick off tomorrow.
While ideally the Blues want to close that gulf in goal difference to become the architects of their own success, if push comes to shove, Robertson said the priority was to secure three points from a victory.
The Rovers have scored 52 goals to Western Suburbs' 42 but the latter have only conceded 10 to the former's 24.
The visitors picked up yellow cards today but no player has strayed into the zone of serving a suspension for accumulated cards.
