"We succeeded in bringing home the player who in the last 50 years has scored the most goals in our shirt.
"President (Silvio) Berlusconi and I am happy, as is our coach and I believe also our players.
"I believe that Milan are the only club in the world to have three European players of the year in our squad."
Galliani added: "Andriy has returned home and I am happy about it. I am a Milan fan and I am very happy.
"I've spoken to Andriy 48 times in the past three hours...the terms of the agreement are very private.
"Andriy made a mistake in leaving and I believe that in the past two years he has realised that this is his home.
"Now he has made his financial sacrifices but at this point the only thing that matters is that he returns to us."
