Mphela’s contract with the Brazilians expires in June next year, making him free to sign a pre-contract with any club from January 1.
A hosts of big names have already expressed their desire to sign the former Bafana Bafana striker, with Orlando Pirates and SuperSport United leading the race for Killer's signature.
Mphela is in his last season with Sundowns, and he has made it clear that he won't extend his stay at Sundowns beyond 2014.
Pitso Mosimane once revealed that he would like Mphela to stay for as long as he is with Sundowns, having formed a close working relationship with the attacker while still head coach of Bafana Bafana.
Mphela is left with a few simple options: sign a new deal at Sundowns and hope to break into Mosimane's first XI; sign a new deal with Sundowns and ask to go out on loan, or sign with a new club when the transfer window opens at midnight.
Mosimane could make life easier for the powerful shooter, by guaranteeing Mphela regular game-time, but it seems unlikely, with Cuthbert Malajila and Katlego Mashego looking set to start the majority of the Pretoria side's games.
But should Mphela opt to put friendships and loyalties aside, a move away from Sundowns would not be difficult to carve out due to the interest shown throughout the year.
Whatever his decision, Mphela will be available to fashion a move away from Chloorkop in about eight hours and could be turning out for a new team midway through the year.
Mphela has made over 50 appearances for the national team and has netted 23 times on the international stage.
