It will not be Milan's biggest signing of the window, but the Rossoneri took Cristian Zaccardo and sent Djamel Mesbah to Parma in exchange.
Zaccardo will offer another option at centre-back, considering that none of Daniele Bonera, Philippe Mexes, Mario Yepes or Cristian Zapata have impressed enough.
Mesbah will likely challenge Massimo Gobbi for a spot on the left of midfield if Roberto Donadoni persists with a 3-5-2 formation, although both could be accommodated down the left of a 4-3-3.
With such a large collection of centre-backs, Milan relinquished Francesco Acerbi, with Genoa taking back the player's co-ownership from the Rossoneri. In a complicated deal, the Grifone turned Kevin Constant's loan deal at Milan into a co-ownership after receiving an additional €4 million.

Genoa have revitalised their squad in an attempt to beat the drop, adding a number of players in their customary bi-annual reshuffle.
As well as Acerbi, the Rossoblu brought in Lazio's Matuzalem, Udinese's Antonio Floro-Flores, Atalanta's Thomas Manfredini, Fiorentina's Ruben Olveira and Palermo Eros Pisano.
Mario Sampirisi (Chievo), Anselmo (Palermo), Alexander Merkel (Udinese), Michele Canini (Atalanta), Anselmo (Palermo) and Felipe Seymour (Chievo) are departed from the Marassi too.
Palermo are the only other club who can rival Genoa for total number of deals made, with Maurizio Zamparini rivalling Enrico Preziosi for madness.
The Rosanero drafted in Nelson (Real Betis), Salvatore Aronica and Andrea Dossena (Napoli), Mauro Formica (Blackburn), Mauro Boselli (Wigan) and Anselmo (Genoa).
Samir Ujkani (Chievo), Luigi Giorgi (Atalanta), Nicolas Bertolo (Cruz Azul), Pisano (Genoa), Mauro Cetto (San Lorenzo), Igor Budan (Atalanta) and Eran Zahavi (Maccabi Tel Aviv) just some of the names that left the Renzo Barbera.
Napoli reshuffled the pack in a bid to challenge for the Scudetto. Pablo Armero (Udinese) and Emanuele Calaio (Siena) came in to replace the departing Dossena, Aronica and Eduardo Vargas (Gremio).
Inter were in the market for a vice-Milito to bolster their attack and the Nerazzurri oddly settled upon Lazio's squad player Tomasso Rocchi.
