Since his return to Premiership action, Mphela has played a key role in the revival of Sundowns, with his two League goals helping the club to move out of the relegation zone.
Sundowns coach Pitso Mosimane will be eager to keep the experienced Bafana Bafana striker at the club and is likely to push to extend his stay at Chloorkop.
"There are no contract talks between Mphela and Sundowns because the club has the option of a one-year extension," Glyn Binkin, Mphela's agent, tells KickOff.com.
"Mphela is currently with Bafana and this is his main priority at the moment," adds Binkin.
Mamelodi Sundowns spokesperson Kabelo Mosito says the club will start dealing with issues related with player contracts next week.
"We are opening our offices on Monday [January 7] so I will be in a better position to comment about contracts during this time," Mosito says.
"All internal matters will only be dealt with next week because we are still on holiday," adds the Sundowns spokesperson.
Besides Mphela, the contracts of Teko Modise, Doctor Mampuru, Method Mwanjali, Musa Nyatama, Esrom Nyandoro, Richard Henyekane and Nyasha Mushekwi will also run out at the end of the season.
