Springboks fans have turned on one of South Africa's brightest stars following Friday night's heartbreaking 21-19 defeat to France in Paris.
Rassie Erasmus's side fought back from 21-7 down but fell agonisingly short at the Stade de France.
And while Manie Libbok's missed conversion proved costly, another Springbok was taking an absolute hammering from supporters.
That man was Sacha Feinberg-Mngomezulu.
More than 640 Springboks supporters have already submitted their player ratings following the defeat to France.
Sacha Feinberg-Mngomezulu has received an average score of just 1.7/5, making him one of South Africa's lowest-rated performers.
Only Damian Willemse (1.6) fared worse.
It was a brutal verdict for a player who had earned a perfect 10/10 from RUCK against Italy just six days prior in Turin.
"Most overrated player in world rugby"
Supporters wasted little time making their feelings known on X..
One fan, @GeorgeHopson9, delivered perhaps the harshest assessment.
"Sacha Feinberg-Mngomezulu is the most overrated player in world rugby."
Another, @angryknob, was equally unimpressed.
"Nope, I don't rate Sacha Feinberg-Mngomezulu. Selfish player with no vision..."
Meanwhile, @adammoursy described his opening 40 minutes as one of the worst halves he had seen from the youngster.
The criticism was not limited to South African supporters.
French fan @pablo_guillen_ admitted he admired Feinberg-Mngomezulu but believed the Springbok had been completely outplayed by Antoine Dupont and Maxime Lucu.
For a player tipped to become one of rugby's great entertainers, it was a sobering evening.
Fans question Sacha's decision-making
The biggest concern among supporters was his game management.
Feinberg-Mngomezulu showed glimpses of his attacking ability but struggled to give South Africa the control they needed.
His kicking decisions also came under scrutiny.
Supporter @Mofurutshe88 questioned his ability to find touch when kicking for the corner.
They also suggested that mistakes were too often excused because of his reputation as a mercurial talent.
Another fan, @SitDaaiInJouPyp, offered a more balanced assessment.
"Sacha can ball. Outrageously talented and still young and developing.
"But all that potential does not guarantee success."
The same supporter later suggested Feinberg-Mngomezulu should study Dupont's ability to pick his moments, rather than simply trying to produce something spectacular.
It was a fair question after a night when South Africa needed control as much as creativity.

RUCK fans deliver brutal verdict
The numbers from RUCK's Rate the Players widget underline just how disappointed supporters were.
The lowest-rated Springboks starters were:
- Damian Willemse – 1.6/5
- Sacha Feinberg-Mngomezulu – 1.7/5
- Jasper Wiese – 1.9/5
- Lood de Jager – 2.2/5
- Kurt-Lee Arendse – 2.4/5
Pieter-Steph du Toit, meanwhile, received 4.1/5, the highest average among the starting XV in the captured results.
RUCK's own writers were slightly more generous to Feinberg-Mngomezulu, awarding him 4/10 in our Springboks player ratings against France.
The fly-half produced an excellent first-half break but struggled to influence the contest consistently.
Erasmus eventually turned to Libbok in the second half as South Africa searched for a way back into the match.
