I think a midfielder (Gerrard out), a fullback (Johnson and possibly Enrique out), a striker (Borini and/or Lambert out) and possibly a CB (depending on how 33 year old Toure is feeling about the prospect of another season) will be the only changes we make this offseason. With any luck we can also sell surplus players like Assaidi, Coates, Alberto & Aspas to try to give us sufficient funds to pursue some real quality in those positions.
CB - Don't forget Ilori & Wisdom.
