Foreign teams are to be investigated following a raid of 18 top-flight Italian clubs by police as transfers done with Serie A sides come under scrutiny.
The Guardia di Finanza investigation is looking into criminal conspiracy, international tax evasion, money laundering and invoice falsification in football.
The police raided the offices of 41 clubs across Serie A, Serie B and Lega Pro on Tuesday morning as part of a probe into a number of illegal activities and seized papers related to contracts between clubs, players and agents at several clubs.
Aside from Serie A giants such as Juventus, AC Milan and Inter, a string of Argentine clubs are part of the quest as well as the transfers of a number of South American players to Italy are included in the investigation.
Milan CEO Adriano Galliani, meanwhile, remains calm as he believes that the probe's focus lies on the 12 player agents involved rather than on the clubs.
"I am calm and relaxed. AC Milan are not the main subject of this investigation. They are just looking at the contracts of a number of player agents," Galliani told Milan Channel.
Inter president Massimo Moratti was equally unworried about the Guardia di Finanza's visit and stressed the Nerazzurri have little reason to worry.
"They’re things from the past, I believe. It’s nothing to worry about."
