Galli, who spent fifteen seasons at the club and won three Champions League titles and five Serie A titles, spoke to Corriere dello Sport about the new era at San Siro.
"It was right of the ownership to make a strong choice and not confirm certain figures," he said. "The objective was to qualify for the Champions League and that objective was not achieved.
"But beyond the result, what matters is the process. And the process left nothing. The football we saw was the only thing that could have saved everything, and the result was not there. It was right for Milan to start again from scratch, and in that sense Amorim can represent a guarantee."
He was clear about what attracts him to the Portuguese manager.
"I like him a great deal. In some respects he reminds me of Arrigo Sacchi β for his idea of football, for his meticulousness in work and for his attention to detail. This gives me great hope."
Galli added a warning about the environment into which Amorim steps. "It will be fundamental to have the support of the club. In recent years we have seen what happens when those who should be supporting a project end up weakening it. Instead of helping the group reach its objectives, it almost became a source of disruption. That is not acceptable."
Asked which current players he would build around, Galli began with a position familiar to him from his own playing days.
"I always mention Gabbia because he represents the Milanismo," he said. He also singled out Adrien Rabiot as a midfielder worth keeping, and took a considered position on the rest.
"On Leao, I have the feeling that the moment has come to close a chapter. Luka ModriΔ can still give a great deal, but it depends entirely on him β I would not let him go with certainty, but I would give more space to the young players as well."
Amorim's appointment was confirmed in mid-June. The Portuguese coach arrives having transformed Sporting in Portugal and guided Manchester United before leaving Old Trafford last summer.
