There was some talk of Milan retiring the No7 after Sheva left for Chelsea two years ago, but Pato has now be handed the coveted number and said: "I am honoured to take the shirt of Shevchenko. The No7 is truly the most important number in Milan's history.
"I want to do great things with Milan, though I know to do this I will have to work hard.
"I am happy with my first week here. I try to follow closely the instructions in training and I know I have a lot to improve."
