This will make a player lose himself, his intuition on the field will wither, and he will no longer possess offensive capability. It's important to know that the young Sotu once had a certain ability to organize attacks, but later lost it.
Such a style even led Sotu, who is three years younger than Maniero, to retire almost simultaneously with him.
This is related to the style of play, Maniero, Gattuso's notorious reputation, and his injuries.
He completely sacrificed himself.
Of course, Maniero never forgot about Sotu's contribution at any time, always mentioning in every occasion that Sotu is his lifelong rival, thus maintaining Sotu's status.
But if it were two other people instead, such selfless cooperation wouldn't have been possible.
Nobody wants to lose themselves, nobody wants to become someone else's satellite, and nobody can believe that their greatest rival in the league would stand alongside them.
