99% sure it's not matchfixing in the sense of 'determining beforehand who wins', but rather matchfixing in the sense of 'Team Y gets the first corner of the game', 'player X gets a booking', etc.
That kinda stuff is apparently pretty common, and it's also the same thing that's going on about in England. They talked about it on last weeks football weekly, and they mentioned that Le Tissier had even admitted that kinda thing in his autobiography.
Also if you think about it, it's not really plausible for anyone too bribe 22 millionaire's to get a fixed result, it makes much more sense to tell one guy to pick up a booking or something similar.
