Both men have been linked with Juventus.
But Lotito says: "Beyond what the market will say, Milinkovic is one of jewels in this club's crown.
“He was named the best midfielder in the League and has enjoyed exponential growth.
“Inzaghi represents the history of this club. He has great potential. He was first a player here and I'll never forget how, when I joined the club, he put himself forward to negotiate his contract, even if there was no need.
“I made a commitment to him that he would be our Coach one day because he was always a player with vision, a point of reference.
“He conquered everything by himself, he won everything at a youth level and slowly emerged.
“I'm taking Tommaso Rocchi on the same route: he's just won the U14 championship by beating Roma 3-0. I'll take him up a level."
