Premier Soccer League CEO, Kjetil Siem, has voiced his disappointment and anger at the way fans behaved at Saturday night's MTN8 first leg semifinal match between Ajax Cape Town and Kaizer Chiefs at Newlands Stadium.

The match was marred by unruly behavior during the closing stages with spectators venting their anger by throwing missiles onto the field causing danger and harm to those on the field.

Disgruntled fans also prevented the match officials from immediately leaving the field once the game had been completed.

"This is not something we want to see or can accept at our matches. It is an absolute disgrace not only towards Kaizer Chiefs and Ajax Cape Town as the clubs involved in the match, but to the PSL and our partners," said Siem.

He added: "What happened on Saturday night could prove disastrous for the whole South African soccer family. It is against the spirit of play and damages the image of our league as well our reputation as hosts of the 2010 FIFA World Cup."

Siem is also wary of the negative publicity this could generate across all media platforms.

"In numerous interviews to international media, I have continuously praised our football fans in this country and underlined how safe visitors should feel when they come to South Africa.

"I also said that our fans have a nice attitude and a constant focus of joy and harmony with singing and dancing, and even children and families should feel welcomed and safe at our games. This type of behaviour we saw on Saturday night reminds me of times where the English hooligans were brainless idiots that nearly ruined a whole industry for its country. I am ashamed," commented Siem.

Siem said with the focus of the international football community on South Africa, the country can ill-afford to show the world such disgusting behaviour.

The Norwegian also praised the brave efforts of PSL General Manager: Football, Ace Ncobo, for his attempts to calm the situation.

"Ace took control of the situation by risking his own safety by climbing into the troubled area in the stands to liaise with the fans and try and calm them down after their match. He succeeded in defusing the situation and I must commend him for that.

"I really hope internal action will be taken and this will never be seen in our football again," concluded Siem.
