Terry Matterson's history with Scotland will not affect his desire to knock them out of the Rugby League World Cup on Thursday night.
Matterson is now in charge of the USA Tomahawks, who have already qualified for the quarter-finals with wins over the Cook Islands and Wales.
They already have their big prize - a last-eight date with Australia - but could deny Scotland the chance to face defending champions New Zealand if they make it three wins from three at the AJ Bell Stadium in Salford.
Matterson has a soft spot for the Bravehearts from his playing days but says there will be no room for sentiment.
"I got picked to play for Scotland in 1998 when I was with London Broncos," Matterson said.
"But I tore my calf the weekend before. I was gutted. I actually went up there with (manager) George Fairbairn and spent a night in camp and then I left.
"My grandfather fought in the war for Scotland. That's the reason I got a work visa, through my ancestry heritage."
The Cook Islands' defeat by Tonga takes the pressure off Matterson's men, but he has no intention of looking ahead to their date with the Kangaroos until their business in the group is complete.
He added: "Our focus is on the Scotland game, we're not getting ahead of ourselves. There is no talk about what's happening after that."
