Lebese scored as a substitute in a 2-0 defeat of Maritzburg United on Saturday, just two minutes after replacing Knowledge Musona, who netted the opener at FNB Stadium.
"We have a competitive squad and we are all fighting for a place in the team," Lebese told his club's official website.
"I was glad to be given an opportunity and that I was able to score my first goal this season.
"I am going to continue to work hard to improve my game.
"My objective is always to help the team and on a personal level, I want to continue to improve and give more to the team than I did last season."
Regarding the victory, he said: "Our objective was to win the game following the games against SuperSport United (3-1 loss) and Moroka Swallows (1-1).
"We are all delighted with the win against Maritzburg United, but we know we have a tough week ahead of us so no one is getting carried away."
The Glamour Boys next face Bloemfontein Celtic at Free State Stadium on Tuesday.
