The four friendlies South Africa played in May 2010 (4 - 0 vs. Thailand, 1 - 1 vs. Bulgaria, 2 - 1 vs. Colombia and 5 - 0 vs. Guatemala) are under suspicion.
The referees for these four matches were brought by Football4U, controlled by Wilson Raj Perumal - now in a Finnish prison for match-fixing. Quite a storm happening now. See more on FIFA.com.
While I'm all against match fixing, the South African press are asking the wrong question:
What role did the now suspicious Bafana matches of early 2010 play in the team's rise in the Fifa rankings? See more on SportLive.
Only the match against Thailand was included in the May 2010 ranking calculation that saw South Africa climb 7 places to 83rd.
