Italy coach Cesare Prandelli says the door remains open to striker Antonio Cassano.
Though Cassano's move from Sampdoria is yet to be rubberstamped, he is already training with the Milan squad.
He said: "Cassano is going through a difficult time. I am certain that once on the pitch, he will prove his worth and will certainly be called up.
"I said I would never abandon him and I keep that pledge."
