Ranieri believes the Nerazzurri have finally put the Jose Mourinho era behind them and are ready to move on.
"The Treble is there, it is in the history books, but doesn't count for us anymore. All that matters is what we will do from here on in."
Inter could even be back in the Scudetto race, as they go head-to-head with leaders AC Milan in the derby next Sunday.
"We are in good shape to face Milan, as the break allowed our players to recharge their batteries. I hope both Wesley Sneijder and Diego Forlan can recover in time for the game, as they can be our best 'new buys' of 2012, although they also have to settle into the mentality the team has adopted in the last few months."
