There is NO evidence whatsoever. Alex Song is innoncent. Case closed.
I don't get how you can find a link when there is no link to be found unless you're so desperate to get him out of the club that you're trying too hard to find one thus making up things to relate to it somehow.
1. I can't be desperate "to get him out of club" because I don't have any powers over that decision.
2. Just because there's no filed criminal charges , that doesn't mean there was no evidence. FIFA is corrupt organization, most likely they will cover-up to avoid negative publicity(They had lot of those in last couple of months).
3. It is really hard to explain why well known match fixer correctly guessed that there will be red card.
4. Your knowledge about about the issue as good as mine, don't imply that you know more than I do.
Again, not every time the crime is persecuted and publicized especially with FIFA involved. C'mon, we are talking about organization which punished Suarez severely for childish behavior and did nothing to Zuniga who almost maimed Neymar. Wait...I can guess your next post"There's no evidence that Zuniga went knee first on Neymar on purpose, he is innocent"
