in: tolisso, alexis, orsolini and meret (both are still only 20, so not relevant to the 25-man squad for an other year)
out: one of lemina/stu/rincon, neto
tolisso can play cm and am, sanchez can play on both wings and as a cf, so allegri would have +2 players for the same 4 spots. also, alves and sandy might be used as backup wingers, too.
btw i watched lyon's both games against roma and their away game @ psg last night. tolisso played as an am against roma (great performance at home, anonymous at roma), and as a cm in a double pivot for their 4-2-3-1 @ paris (an other good game for him personally, despite the loss). i'm starting to be convinced that he'd be a good addition.
