The former Göztepe and Platinum Stars striker might leave Ajax Cape Town in a swap-deal that would see SuperSport's Mabhuti Khenyeza going the other way.
But Grobler, who scored 13 goals in the 2009/10 season, says he remains committed to the Urban Warriors.
"There is not really much I can say about that [a possible move to SuperSport United]. There will be a time when I will be able to talk more about this," Grobler tells KickOff.com.
"I am just focusing on my game. I am still an Ajax player and I am committed to the club. We have been practicing hard and I am happy with my physical condition," he adds.
Grobler has only scored three goals so far this season and a move to SuperSport might give him a new lease of life.
Khenyeza – on the other hand – is clearly unsettled at SuperSport.
The 30-year-old striker is yet to report back to the club for training this year.
Gavin Hunt recently confirmed to a local radio station that SuperSport and Ajax were busy with the paperwork that would result in Grobler and Khenyeza swapping bases.
Ajax Cape Town chief executive George Comitis could not be reached to shed more light on the likelihood of Grobler's departure as he was in a meeting.
