Adriano Galliani has extolled club supremo Silvio Berlusconi for signing Ibrahimovic and Robinho.
The Rossoneri landed Ibrahimovic from Barcelona on a season-long loan with an option to purchase him outright and on Tuesday signed Robinho from Manchester City on a four-year contract.
Speaking to Sky Sport 24 on Tuesday evening, Milan's Galliani said, "These two signings were a great present to all the supporters from Silvio Berlusconi.
"Robinho will wear the number 70 shirt, Ibrahimovic will have the No. 11. Robinho cost €18 million plus bonuses.
"For so many years I have not seen Berlusconi so in love with Milan. On Sunday Ibrahimovic told me to go and buy Robinho also."
Ibrahimovic's agent Mino Raiola added, "I never spoke with Milan about Maxwell. He is very happy at Barcelona."
On Tuesday striker Marco Borriello left Milan to join Roma and told Sky Sport 24, "I am happy, it is an important move for my career. I will speak more tomorrow."
