Coetzee joined Sundowns last season after a move to Scottish giants Glasgow Celtic fell through due to an underlying foot injury which was discovered during his medical in Europe.
His move to Chloorkop was sealed on the final day of the transfer window, but he was unable to play the entire season due to the problem he had.
Coetzee, however, recently played in Sundowns' MultiChoice Diski Challenge match against Maritzburg United, which they won 3-0.
“We as Mamelodi Sundowns players are happy to see him getting minutes on the pitch after a long time not playing. I am happy for him,” Kekana tells KickOff.com.
“Rivaldo is a talent who, in my eyes, can play anywhere in the world. We will be happy to see him 100 percent fit so that he can help us because we need every player at this stage of the season.”
Should he get to a stage where he is fully fit to compete for a place in the first team, Coetzee would have to overcome some serious competition to play in central defence, against the likes of Motjeka Madisha, Mosa Lebusa, Ricardo Nascimento and Wayne Arendse.
