Italian police have today opened an investigation amid allegations of irregularities in Luis Suarez' citizenship exam last week. 

The former Liverpool striker flew to Perugia last week to take the test ahead of a potential switch from Barcelona to Juventus, with Juve needing him to become an Italian citizen in order to meet squad limit rules.

It's claimed that the Uruguay international was made aware of the contents of the exam before taking it, and that his score was pre-assigned.

"Some irregularities have emerged in the exam of certification of Italian, sat on September 17 by Uruguayan football player Luis Alberto Suarez Diaz, needed to obtain the Italian citizenship," Perugia public prosecutor's office announced.

"From the investigation, it emerged that the topics in the exam had been agreed in advance with the applicant and that the relative mark had been attributed even before carrying out the exam, regardless of the fact that an elementary proficiency of the Italian language had been verified during remote classes carried out by lecturers of the University for Foreigners.

"Today, the Italian financial police are moving forward to capture the documents at the university offices, to verify the actions described beforehand and notify the information assurances for the crimes of revelation of professional secrecy, false representation committed by public officials in official documents and other."

Alvaro Morata's transfer to Juventus yesterday is likely to pave the way for Atletico Madrid to sign Suarez on a free transfer from Barcelona.
