Funny thing is it's not bashing. It's absolutely the truth. But since benfica is the biggest club in the country with 6 million potential supporters, it's natural to have lots and lots of supporters working as oppinion makers on the tv, working in the police, the law system, the football federation and in the referee counsil.
There are hundreds of evidence cases showing they are cheaters, paying adversary players to lose the game, having players with doping, paying referees, paying television hosts, "gifts" to members in the government, money laundry with agents, etc.
Benfica president is a fellon and convicted for it, he stole a truck 20 years ago. Because they are so many and with so much power, these informations are often shushed.
