Throughout the 2023 Hollywoodbets Super League season, UWC are the only team to have put up a challenge to champions Mamelodi Sundowns, but a surprise loss away at Richmond United two weeks ago put a major dent in their campaign.
With two games remaining, the Blues have won 24 of their 28 matches, conceding the least amount of goals (14) while scoring 63, compared to Sundowns' 84 – a figure Mbuli feels could be their Achilles heel in the title race.
"We are proud. I don't want to lie to you, we said we need to improve our numbers, our problem in the last few seasons was drawing game – we didn't draw a game this season," said Mbuli.
"Until now, we're a team that conceded the least goals, the only problem now is scoring goals – you see, when you play a game as a coach, if you don't know your problem then it becomes another problem because you don't know where to solve.
"Our problem is clear, it's up-front and we must fix that if we want to maybe challenge Sundowns, even next season."
UWC beat JVW 1-0 on Sunday to move six points ahead of Sundowns Ladies, who have three matches in hand, and will therefore need favours from other teams if they are to dethrone Banyana Ba Style.
For the first time since the competition's inception in 2020, the dominant Sundowns, who were named CAF Women's Champions League winners last night, have not yet sealed the league title before their continental exploits, thanks to UWC.
"I said to them at the beginning of the second round, no matter what happens, come 26 November, we must look back and say we are proud," she added.
"No matter what happens now, it's no longer in our hands, but if we look at the past three seasons, we should be proud of how we've done this season."
