Republic of Ireland manager Giovanni Trapattoni thinks the title race will come down to a photo finish, but still believes Milan will hold on.
This weekend's Derby della Madonnina is being billed as a title decider with Inter just two points behind the League leaders at the business end of the season
Interviewed by La Gazzetta dello Sport, Trapattoni said: "I like Max Allegri. He has been a wonderful surprise. In the summer everyone was convinced that he'd play five or six strikers to make Berlusconi happy. Instead Allegri has changed Milan's mentality. He has convinced his champions that first they must win the ball then try and fling it in the back of the net.
"An illogical team has all of sudden become a title contender thanks to three words: spirit of sacrifice. Let's put it this way. This time Milan-Inter seems like a Champions League game and in the Cup the great Zlatan has never made the different. Eleven players must win the derby then Ibra will resolve the remaining games by himself.
"If Milan want to win the Scudetto they must stop Inter now in the derby. If Leonardo overtakes Milan the title race is over. The Nerazzurri would become like those American aircraft carriers that win all the wars. Unassailable."
