For the second year in a row, reigning African champions Al Ahly have fallen short at the semi-final stage of the FIFA Club World Cup after the Egyptian giants were downed 2-0 by Brazil's Palmeiras on Wednesday.
The defeat consigned Mosimane's charges to the third-place play-off (the stage at which the club coincidentally defeated Palmeiras last season) where they will meet the loser from the other semi-final clash between Al Hilal and Chelsea.
Despite the prospect of another podium on the cards, the former Mamelodi Sundowns boss was disappointed not to have gone one step further than the heroics he achieved with the Team of the Century last season.
"We hoped to be in a better position than last year, this year, but we are in the same position, the semi-finals, as we were last year, coincidentally [losing] with the same scoreline. That means we have to improve, we haven't improved in that sense," Mosimane told the media.
"We didn't start very well. I think we could have started a bit more forward with the team, but we gave them a little bit more respect. We could have started better than the way we start and, in fact, we were a little bit more forward when we were 10 against 11 than we were at the beginning.
"I'm disappointed because we let ourselves down with the red card and that was the time when we had the momentum hoping that we could get a goal and we looked like scoring.
"We got the ball of the post and, I don't know it looked like a penalty [as well] but I can't say. If VAR also thinks it's not a penalty, we have to respect that.
"But we started a little bit late in the second half. In fact, it was immediately after we conceded a goal, then we started to play stronger in the second half. But what can you do? We played a good team. They have a little bit of quality, they were a little bit stronger, a little bit fresher."
