Speaking at a press conference on Friday, May 20, Richard said: "I think if we can get a result tomorrow it will probably be my biggest achievement in football."
And he also revealed that he expects to make a return to management in the future.
Gough said Livingston would be playing positively in possibly their biggest ever match. "We've had a couple of good results against Dundee," he added, "and there's no way we'll be playing for a draw tomorrow, we'll be going for the win."
The manager said he hoped to leave incoming manager Paul Lambert in the Premier league. "I don't really know him that well," he added, "but he seems a good fellow and Archie and I will be doing our utmost to ensure he's still in the Premier League."
Reflecting on his time, the manager commented: "I was employed to keep the team in the division and if we can do that it will be a job very well done. All credit to the players, they have worked really hard.
"Archie's been at Manchester United, Everton and Rangers all big, big clubs, and he said this four or five months has been the hardest job he's had."
Gough warned that Saturday's game would be another cup final for the club. "It's a day for heroes," he added.
