Cape Town - Platinum Stars coach Cavin Johnson believes his players let themselves down in the 2-0 loss against SuperSport United on Sunday.
Two goals in the first half from Mario Booysen and Kingston Nkhatha secured the win at the Royal Bafokeng Stadium.
Johnson was disappointed that his team was unable to excetute in front of goal as the third-placed Dikwena suffered their fifth loss in the Absa Premiership.
"I thought we didn't do well in the first half. The goals that came destabilised us - they were two set pieces, and we spoke about this. When you are not switched on for 90 minutes, you are punished," Johnson told KickOff.
"The biggest thing we do at training is finishing. I think it's the tenacity and nerve when you get in front of the poles, who you playing against and who is in the poles, and all those little factors come into play, and players need to come to the party at that stage."
