And the Juventus chief further irked onlookers this week with his crass comments about Atalanta's run to the last eight of this season's competition.
Agenelli said: "I have great respect for everything Atalanta are doing, but without international history and thanks to just one great season, they had direct access to the primary European club competition.
"Is that right or not? Then I think of Roma, who contributed in recent years to maintaining Italy’s ranking. They had one bad season and are out, with all the consequent damage to them financially.
"The point is how we balance the contribution to European football and the performance of a single year."
Established European clubs outwith the top five leagues are increasingly concerned over proposed changes with Celtic's Peter Lawwell and Ajax's Edwin van der Saar fighting their corner at boardroom level.
Agnelli, despite his long standing desire to shake up the Champions League, is understood to be willing to safeguard European regulars like Celtic and compatriots Rangers if his revolutionary plans are rubber-stamped.
