The Team of Choice put in a good first-half display before coming back late on to secure a comfortable 3-1 victory over relegation-threatened Bakgaga on Friday evening.
Lentjies welcomed the result but admitted to SuperSport TV that they need to learn to deny their opponents a way back into the game after dominating the first half.
"We made it difficult for ourselves, but we just want to give all the praise and glory to God for carrying us through, coming out injury free," said Lentjies.
"So we'll take the three points but we must learn from is, when we were leading 2-0 we seemed to lose momentum a bit. We started off well and the third goal was just... I breathed a sigh of relief.
"Yes, we deserved the three points today I think, but it's a match that we should learn from."
Though they managed three goals, Maritzburg had plenty of chances to kill of the game and Lentjies reiterated their need to take their opportunities better, while also praising his troops' teamwork.
"We must learn to kill teams off, but three goals at home [is good]. The goal we conceded was a bit of a soft penalty," he added.
"Kwanda was giving everything and he also deserves man of the match, he played really well. He showed he's fighting for the team and putting the team first.
"That's what we did today – we sacrificed ourselves for the team, even when things didn't go well we worked hard as a unit, and we give God all the praise and the glory."
