The FIFA agent Giorgio Ghirardi said in a recent interview with ilsussidiario.net (h/t SempreInter) that he believes that Inter players Marcelo Brozovic and Andrea Ranocchia could be on their way out of Milan come January:
In January there won't be a player coming in just for the sake of buying. Mancini will choose with attention, especially for midfield. Should reinforcement arrive it will be a quality one. Pirlo is of course an important player that could be very motivated to return to Italy and win another scudetto with yet another Italian team, Inter. Brozovic could be sold, he is very well liked in England and Inter could cash in on him. Bologna after Biabiany? I don't think Mancini wants to let the player go, he is doing very well during this part of the season. The redemption fee for Ljajic? It is too early to talk about that now, Inter will decide in April or May. In January either Vidic or Ranocchia will leave Inter, I think it will be the Italian who leaves.
As you'll notice, Ghirardi explains that Mancini is not interested in buying a player he does not need. If Inter do indeed try to cash in on either Broz or Frog, it will be because Mancini has a very particular talent in mind. Now, do I think that talent in question is Andrea Pirlo? Absolutely not. I still put no stock in any of the Pirlo claims. If it happens, I promise to eat my words, but I just don't think it's likely.
Now, regarding Marcelo Brozovic: I'm not sure how I would feel about him leaving. He is just beginning to develop into the type of player that Inter need him to be. Unless Mancini is able to cash in on Broz for a pretty penny, I just don't think it's worth selling him in order to start over with yet another midfielder - especially when Broz finally seems to be finding his groove.
