The Serie A side's vice-president, Adriano Galliani, reveals the details of the midfielder's contract and is delighted to get his man following failed attempts in the summer
The Japan international's move from CSKA Moscow was finalised on Wednesday following a drawn-out transfer saga that has lingered since the summer.
Honda, who has signed on a free transfer, with his contract in Russia set to expire in December, could make his debut against Sassuolo on January 12 and Galliani is delighted to have captured his target, though he distanced himself from speculation surrounding Parma midfielder Marco Parolo's future.
"Honda's an excellent player who has always done well up to now," the club's CEO told reporters on Friday.
"He is presently in Japan but he will join up with us on December 30. He has signed a three-and-a-half-year deal that will expire in June 2017.
"He has asked for the No.10 and we have given it to him. I do not know anything about the Parolo rumours."
The Honda deal ends what has been a good week for Milan as they confirmed their place in the last 16 of the Champions League, finishing runners-up in Group H.
The Rossoneri were the only Italian side to qualify for the next round of the competition - for which they will find out their opponents on Monday - with Napoli and Juventus both dropping down to the Europa League, and Galliani is proud of the club's achievement.
"That competition is in our DNA," he continued. "History shows that; we are the only Italians in the Uefa's top 10 club ranking. For the future coefficient, we'll have to look out for Portugal.
"Juventus's game at Istanbul? It was a tie that should have been postponed. You could not play football on that pitch."
