Old rivalries are renewed as the ex-midfielder leaps to the referee\'s defence and claims Claudio Ranieri\'s men only have themselves to blame for defeat.Former AC Milan playmaker Zvonimir Boban has unleashed his anger at Inter for the way the club was highly critical of referee Gianluca Rocchi\'s performance in their 3-0 loss to Napoli.Claudio Ranieri\'s men were hammered by Napoli, but Inter felt it was Rocchi who contributed to them being pinned down at San Siro following a number of decisions he made, including the sending off of Joel Obi, and subsequent penalty award.President Massimo Moratti said the referee \"ruined\" any chances his side may have had and suggested Inter are always under threat when Rocchi is in charge.However, Boban has reacted and he believes the former champions are taking complaints too far as old rivalries are renewed.\"The referee? To be honest, I am very surprised as to why Inter are complaining,\" Boban told Sky Sport Italia.\"The Inter players are saying they are the victims of poor refereeing, but I feel this is all exaggerated.\"Inter did nothing worthy of mention during the game, where as Napoli always looked dangerous when they got close to goal.\"Boban\'s former club Milan meet Juventus on Sunday night in Serie A.?
