Milan midfielder Mark Van Bommel doesn't think the Derby della Madonnina in April will be decisive in the title race.
Inter are five points behind the League leaders, but have generated a great deal of momentum since Leonardo's appointment in December.
Speaking to Sky Italia, Van Bommel said: "The derby is an important game, but I don't believe that it will decide the season.
"We still have many games to play. We must concentrate on Juventus, on Tottenham, and then one Bari and on Palermo.
"Massimiliano Allegri is a good Coach. He is very calm.
"It's always a great emotion to play against Juventus. It's wonderful to play this kind of game and for me it will be more emotional because there is my friend Hasan Salihamidzic.
"They have lost many games, but these matches are more complicated because everyone believes that we will win them.
"I am telling you that it won't be easy also because we'll play them at their home."
