In terms of goalkeepers, I can't see either Cech or Hilario leaving; both are happy at the club or so it seems.
I think we might see a few defenders go. Ivanovic's agent says the player is happy but he has since lost his place in the team, although Ancelotti did want to bring him to Milan and clearly likes the look of him. Ferreira might leave as well, although he seems happy being at the club and is ready to play as and when we need him. Belletti might be off as well, even though I would like him to stay. He does like playing Spurs, of course. Bosingwa has been linked with going but I can't see it happening at all tbh, after having such a great season. Carvalho looks like he is on his way too.
I can't see any midfielders leaving bar the obvious - Mineiro's contract is up and Deco's a certainty to leave. I don't see anyone else going, in all honesty.
Di Santo is likely to go on loan and Pizarro and Shevchenko will most likely be sold, although I personally want Shevchenko to come back. There's reports linking Kalou with a move but I don't think he will go either.
