Northampton Town manager Keith Curle says the squad took inspiration from Arsenal's 1989 win at Liverpool as they prepared for the play off semi final second leg.
In that match at Anfield, the final game of the season was between the top two in Division One, the Gunners needed to win by two clear goals to take the title, something they achieved against all the odds.
Curle said he had shown his players clips of the recent Sky Sports documentary about that match in the build up to Monday night's game.
"When I came here, on the back of a relegation and being third from bottom in the league, I said to the Chairman I wanted to make this club competitive and we have done that," he said.
"From day one, we have started to compete and that is something that is growing.
"For Monday night, it was all about being positive and having the right mindset. We showed the players clips of the Sky Sports documentary from 1989 when Arsenal beat Liverpool to win the league.
"It is not an easy thing to do, to go away and win by at least two goals. If you believe and you have a plan and you execute that plan then you have a chance. The first goal was vital, we got that and we could put Cheltenham under pressure.
"We know only too well to our cost that you never go home when a game is 2-0, it is not over. It can change quickly and it changed in our favour on Monday night.
"It is about belief, and understanding what you can do. If you believe, you are one step closer to doing what you need to do."
