Controversy is never far away from Luis Suarez.

From deliberately getting sent off for handball at a World Cup, biting opponents, being found guilty of racially abusing Patrice Evra, the Uruguay striker has been seminal in some of football's more unsavoury incidents over the past decade.

It was announced Tuesday that the 33-year-old is being investigated on suspicion of cheating to pass his Italian language test with the help of his teachers by prosecutors in Perugia.

The Italian exam was a first step required in order to receive a passport ahead of a potential transfer to Juventus, a move which has since been abandoned, from Barcelona.
