Vieri, Inzaghi, Zanetti C., Gattuso and Tacchinardi won't be part of the team.
Vieri - still out on injury
Inzaghi - will not accept the call up (speculation is that he is still angry at Trapattoni for leaving him as a reserve behind Corradi and Miccoli in the previous friendly)
Zanetti C. - Got injured during training on Monday
Gattuso - Feels humiliated when against Wales he started as a reserve, the Trap sent him on to the pitch, but after just 15 mins he substituted him for another player. Anyone who played or plays football knows that this is the ultimate embarassment in football.
Tacchinardi - After being left out and forgotten during the whole last year and most of this year, Tacchinardi declined the call up for the Portgual friendly, and he will unlikely accept this call up too.
Most of these players won't play for the national team again unless they patch up with Trapattoni or there is another coach.
I'm sorry, but if that's the reason Gattuso would refuse a call up, that's pathetic on his part. When he came on the pitch against Wales, it was 1-1. Wales scored 5 minutes later, and then 20 minutes later, they needed another offensive option, so a defensive midfielder(Gattuso) was taken off for a forward(Marazzina).
If that's really the reason Gattuso isn't accepting calls, he needs to check himself. It's not about him.
