Basically.
A 35-year-old (36, this coming season) striker isn't meant to be a focal point in terms of restructuring a team; which is exactly what is required, unfortunately.
A good spine to build upon would be - Buffon, Chiellini, Marchisio, Melo, and Diego. Pretty thin, however, so I would also count on Manninger, Poulsen, and Iaquinta. If loans are sorted, Caceres and Candreva, as well.
