To be honest, this player at Milan makes me turn up my nose a bit. It doesn't seem normal to me to take such an old player to play him in a team that needs to be reborn. They're basically doing what they did with the phenomenon Ronaldo. I certainly don't like the choice, but maybe he can surprise me again, who knows.
This is a common thing for Milan, remember how Ibrahimovic played for Milan at 40 years old, and frankly speaking he spent most of his playing time on the bench with injuries, rather than playing, but he remained their player. Unlike him, Modric at his age is still in good shape, and he very rarely gets injured, so I think that Alegre will not refuse such a player, especially in conditions of limited finances for new transfers.
