Men the Paisley gaffer can trust to get his message across on the field of play, get the job done and bring a first major trophy back to the town after an absence of 26 years.
Lennon will take succour from the knowledge that skipper Jim Goodwin will provide leadership, that maverick playmaker Paul McGowan can supply a touch of genius that can win the final outright with one piece of skill.
In goal, Craig Samson proved by saving a penalty against Celtic in the semi- final that he can make a match-saving contribution.
Yet it is the talismanic presence of top scorer Stevie Thompson – who fired the semi-final clincher against Celtic – which will do most to bolster Lennon's belief that the League Cup will be dressed in black and white ribbons by teatime on Sunday.
That is because the striker is a proven winner when it comes to the big games.
The 34-year-old has won a league title, a Scottish Cup and a League Cup with Rangers, played in a FA Cup final with Cardiff, fired Burnley up into the Premier League and bagged 16 Scotland caps.
However, it is the prospect of helping his hometown team end their trophy drought that would provide the crowning glory of an illustrious career for him.
Thompson said: "I guess I have been lucky to have played in so many big games and won a few trophies with Rangers.
"I then went on to play in an FA Cup final with Cardiff and backed that up by winning promotion at Wembley with Burnley to the Premier League.
"But I have no hesitation in saying that to hoist the League Cup with St Mirren on Sunday would top the lot.
"When I came to the club a couple of years back I had a dream that maybe we would make it through to a final but at the same time I never really thought that would happen.
"But now we are at Hampden on Sunday we are there to win the League Cup and personally speaking I just can't wait to walk out onto the pitch in front of all my family and our support.
"It will, without doubt, be the proudest moment of my career."
Thommo, who has banged in 14 goals already this term, believes that the Portuguese striker Esmael Goncalves can play a crucial role in Saints assault on the silverware this Sunday and is confident he will once again revel in the wide open spaces of Hampden, much like he did against Celtic in the semi-final.
The Saints striker said: "Esmael has that touch of the unpredictable about him. When he made his debut against Celtic they did not really know how to play him and that is because he is capable of doing a variety of things with or without the ball.
"Obviously he is more of a known quality now but he loved the extra space at Hampden and depending on how we line-up he will probably have another key role to play for us on Sunday.
"But you look at the pedigree he has and the clubs he has played for and it is no surprise he is capable of producing that type of quality.
"I think the great thing for us is that he has come in and given us that something different. We already had good competition for places with myself, Lewis Guy, Sam Parkin and Dougie Imrie but Esmael is different to all of us.
"He is undoubtedly a big game player and in my opinion that will mean Esmael will be at his best on Sunday."
St Mirren came out on top in their most recent meeting with Hearts but when it comes to what they can expect from the men in maroon on Sunday the Paisley talisman has no doubt that encounter can be ignored.
Thompson said: "I think if you look at both the content of their team and the results they have had since Gary Locke has come in then you can see that he has galvanised them.
"I think what you will get on Sunday is two hugely committed sides who will leave nothing in the locker in pursuit of the cup.
"If, like we did against Celtic, each one of us can play to our best we will give ourselves every chance of ending all these years without silverware since the Scottish Cup win of 1987. That is something I will be bursting a gut to do."
