[11] Agreement was reached in early March 2010 to allow Italian teams entry to the Celtic League in time for the 2010–11 season.

[12] The clubs will also be guaranteed places in the annual Heineken Cup, which had previously been awarded to the two top teams in the National Championship of Excellence.

The fact that the Six Nations decider in 2009 between Wales and Ireland featured 42 Celtic League players out of 44 in their squads supported this notion.

[13] After initial applications in 2010, it was proposed that Aironi would join along with a new team, Praetorians Roma,[14] but Benetton Treviso were nominated instead.

[15] However, Pretorians Roma failed to satisfy the evaluators of their financial muscle and Benetton Treviso were nominated in their place.

[16] Aironi struggled in their first season; a surprise European Cup win over Biarritz was the only highlight of a campaign in which they managed only one Pro12 victory.

[17] The Federation decided against another domestic Italian club taking over the running of the licence, instead opting to maintain complete control of a planned new franchise.

The name had been used by an invitational select rugby union team based in Northwest Italy that played regular fixtures between 1973 and 1997.

The opening match was an unofficial test played in Milan in 1973 against the Australian team of Randwick Sydney, who won 21–50.
