Gattuso, known to us as Rino, is a very strong-willed person and very consistent in achieving his goals.
And what goals did he achieve?
Palermo - sacked!
Pisa - sacked!
Napoli - sacked!
Valencia - sacked!
Marseille - sacked!
Special mention that in one of his few tries, when he managed to stay for more than half a season without getting kicked out, was when he managed to cling to his seat at AC Milan, where he finished 6th and then 5th.
He hasn't achieved anything, and with how the Italian team looks right now, prepare for more disappointments!
