AC Milan coach Massimiliano Allegri says this summer's revamp was inevitable.
Allegri's squad has experienced a massive clearout in recent months.
"We needed a generational change," Allegri told La Stampa. "It might not be nice, but that is how life goes.
"I too would have liked them in my squad when they were seven years younger
"It takes courage to make the painful decisions that Milan made, but to keep speaking about these champions is disrespectful to those players who have remained."
