As an Inter fan, we need to see the bad side of our team: fighting spirit. Before Mourinho and during lots of Mourinho matches, players walk and play sleepy during the match. The derby yesterday is not an exception.
During Mourinho era, we improve a lots in terms of fighting spirit. We won several matches after being leaded by the opponents. Then it declines during Benitez. Leonardo is a good coach in boosting the player spirit but unfortunately is not as good in tactics. Now comes Gasp, and I doubt that he is the coach strong in motivation.
Besides the coach, the captain and senior players like Cambiasso and Deki are very important to push players. JZ is an Inter legend. But IMHO, he is not the type of captain who pushes players. Milan's Gattuso looks very stupid compared to him. However, Gatusso would kill someone who does not give his best to the team. Another examples is Victor Valdes, who is crazy sometimes but it makes the team better for the fights.
Do not forget that Mou always do crazy things, sometimes sounds stupid, but it it intelligent stupidness, which constantly put player under force to fight for the team.
For me, the current environment of Inter training, changing room, captain, coach has nothing positive to have better fighting spirit. It is too static, too gentlemen. Deki is the one i would made him to be a captain but unfortunately he is not the starting material.
