Crime: Connections with Al Qaeda, assisted in carrying out Paris attacks
Jail time: 10 years
This guy beats all footballers in this countdown, because while the others were busy driving recklessly, assaulting people or being involved in tax-frauds, this guy had connections with the terrorist organization Al Qaeda! He made just one league appearance and scored a goal. He was later proved to have plotted an attack against American soldiers who were deployed in a Belgian airbase. He was also sought to be the suicide bomber who would carry out the attack in Paris!
