The message that hard work pays off is illustrated in Sibiya's rise to prominence this season and a call-up to Bafana Bafana's provisional squad for the COSAFA Castle Cup which will start in the few days' time in the North West province.
The national side are defending champions, having defeated Botswana in the final in last year's event.
As defending champions, they'll enter the tournament in the quarter finals where they'll face the winner of Group A which comprises of Malawi, Tanzania, Mauritius and Angola.
The 22-year-old produced a particularly eye-catching performance in the Nedbank Cup round of 16 against Mamelodi Sundowns when a moment of genius allowed him to turn Motjeka Madisha and race towards goal before calmly slotting past Kennedy Mweene.
In the league Sibiya made 16 starts and netted twice for Abafana Bes'thede as they finished in the top eight for the first time since 2009.
Larsen says seeing Sibiya's name in the Bafana's squad was not surprising following his performance last season and urged him to believe in himself and not be affected by stage fright.
"No, its not a surprise. I think if you look at how he performed last season he really came to the fore in terms of his performances and establishing himself as a good player in the Premier League," Larsen tells KickOff.com.
"I think it it is fully deserved. The only advice I can give him is just continue what you have been doing. You know he's growing every game that he plays, he's getting more and more confidence and he's starting to believe in himself.
"He's just got to continue with that in believing in himself, his ability, and I'm sure that he's got a bright future ahead of him."
Larsen feels Sibiya's call-up will encourage other young players at the club to work harder and feels as the coach his work is starting to bear fruit.
"This is also motivation to other youngsters when they see how well he [Sibiya's] done and it motivates them as well to work harder to try and achieve the same thing he's achieving," he added.
"I think this is a good thing for everybody and for all the youngsters at the club."
