Ahead of Juve's clash with Inter Milan this weekend, Ranieri drew comparisons between Abramovich and Inter chairman Massimo Moratti.
He said: "Juve must beat Inter. Nobody wants to be bored until May like last season. Moratti is a president blessed with a lot of money, but he is also determined and loves football.
"He's not like Abramovich, who saw one football match and decided to buy a team at random."
