After the departure of former coach Rulani Mokwena, Mamelodi Sundowns have continued to be exposed in one area, a specialization that has remained vacant.
Sundowns dominated Magesi in the Carling Knockout final but were undone by two goals from crosses that handed Clinton Larsen's charges a 2-1 victory.
After going a goal behind in the first stanza, Tshepo Kakora pulled Dikwena level with a free header early in the second half after a cross by Edmore Chirambadare.

Delano Abrahams also was unmarked when he fired home the winner for the Limpopo outfit in the dying minutes after a flick from a corner by Samuel Darpoh.
The men in Yellow and Blue appear vulnerable on set-pieces and crosses into their box, after they lost 1-0 to Polokwane City in their first round clash in the Betway Premiership, where Bulelani Nikani flicked a long set-piece to upset their more fancied opposition.
The Tshwane giants also almost dropped points against Royal AM in the league.
Going into the dying minutes leading 2-0, Sbangani Zulu reduced the deficit for Thwihli Thwahla with a header from a corner and John Maduka's men had a similar chance, after getting a free header in the box in added time, but fortunately goalkeeper Ronwen Williams made a save.
"The only sad thing is the goals we conceded, because it's the areas we worked very hard on and we identified, particularly the first goal," head coach Manqoba Mngqithi said in his post-match press conference on Saturday.
"We knew that Chirambadare's crossing precision is good and it was unfortunate for Mothobi [Mvala] in the far post to have both [Tshepo] Kakora and [Wonderboy] Makhubu at the same time and he made the mistake to try to jump to the one who was in front of him and the ball was played behind. That's how we conceded the first goal.
"On the set-piece [of the second goal], we were even worried that it would be Makhubu who would come short at the near post. We were clear in our instructions that we should not allow anyone to edge us in the near post with a flick," he emphasised.
"It was unfortunate we were edged by even a shorter player Darpoh, who came in front of Lucas [Ribeiro Costa] and had that flick and unfortunate behind that we did not look good in terms of marking, because Abrahams had a clear tap-in," the former Golden Arrows coach added.

The Brazilians are yet to replace Michael Loftman, who was the set-piece coach under Mokwena and was not retained following the latter's exit at Chloorkop.
It is understood that goalkeeper coach Wendell Robinson has been assigned the coaching duties of set-pieces as well.
