The Kaizer Chiefs forward was speaking to Football411 ahead of Saturday's international friendly against Malawi in Durban and he says Bafana may have found an answer to their goal scoring problems in Rantie.
According to the football411.com website, the 22-year-old, who plays for Malmo in Sweden, has scored two goals in four matches for Bafana since making his debut back in June in a World Cup qualifier against Botswana, and Parker expect more of the same from the striker.
"We have a lot of good players in the squad and in terms of our attack, I have been very impressed with Rantie after being with him in past camps. I think he's got a good future if he can stay focused," Parker said.
"I actually don't consider myself an out-and-out striker and him being an outright striker, I think he can do more for the country.
"The thing I like most about him is his movement, so he makes the right moves and he is a strong guy, meaning he can deal with the defenders. I haven't seen much of his technique, but from what I have seen he's got a bright future in the game," Parker added.
Rantie and Parker are likely to start for Bafana against Malawi, but Chiefs coach Stuart Baxter has warned that Parker has not fully recovered from twisting his ankle against University of Pretoria recently - this despite coming off the bench to score Amakhosi's second goal in the 2-0 defeat of Amazulu in midweek.
