I'm talking about the absolute regulars, such as Koscielny (who has been linked with a move already) Jack, Mikel, Theo etc. (and yeah, I realize most of them have signed new contracts, but well, that hasn't stopped anyone before)
I could do without Gervihno, Santos and even Podolski (if they do bring up Higuain or Yovetic) but I never counted them as indispensable, anyway.
I certainly wouldn't like to see Vermaelen departing, yes, he had a crappy season but he's a good player, though I could see him leaving to find his form again, given that he will struggle to get into the XI with Mertesacker and Kos co-operating so well.
