And Little is now hoping to emulate the Gers gaffer's staggering strike rate in Old Firm games by netting against Celtic at Parkhead on Sunday.
The Northern Ireland internationalist is certain to start the SPL showdown after a stunning run of form.
He has banged in five goals in his last seven games and netted a double in the 3-0 win over Hearts at Tynecastle last weekend.
It is a remarkable haul for a 22-year-old who has been dogged by serious injuries.
The versatile star, who can also play in defence or midfield, has told how watching manager McCoist at Murray Park has been invaluable for his finishing.
Now he is hoping his boss's incredible Midas touch in front of goal against his team's city rivals – he netted 24 times against the Hoops – rubs off on him.
Little said: "The manager has been very helpful to me. When you hear somebody like him telling you that you are a goal threat, that you are going to get a goal, that he is full of confidence in you, then it fills you with self-belief. You can't ask for much more than that.
"I have learned a lot from him. He trains with the boys on the odd day and I can see what he does, how he moves and works in the opposition penalty box going forward. Let's face it, there is nobody better for me to learn from.
"I am full of confidence that I can score whenever I play. I always scored goals when I was younger. I am finally getting a run of games in the first team now. I couldn't really be expected to score goals before when I was coming on for the last 10 minutes or so of matches.
"I think I am a goal threat and I am delighted I am getting games now. I have scored four in five matches and I have got five in seven since coming into the team. It is brilliant to finally be getting a game. I am just delighted to be getting a run.
"This is what I have wanted since I have come here. I am injury-free and feeling good and am looking to keep scoring goals in every game between now and the end of the season."
Little banged in his first goal in the Old Firm game in the 3-2 win over Celtic at Ibrox at the end of last month and is confident he can hit the target against them once again this weekend.
He said: "We are in good shape as a team going into this game. We have won four-in-a-row against Celtic, Motherwell, St Mirren and Hearts, and confidence is high we can get a win and give our supporters something to cheer about on Sunday."
