Anderson/Wharton/LWB (or even RWB imo..)/Thiago (instead of Zirzkee). Thiago and Sesko as our striking options would not be bad at all, would it? In terms of midfield, if we can get those two, we're sorted for a decade with Casemiro, also, on a reduced wage (and Maino) ensuring good competition and rotation options. The LWB is an interesting one. I would have said RWB (or RB who can go forward, more than anything) is the issue.
But the thing is, and people neglect it, we need that above quality in said positions regardless of which manager comes in next. Everyone knows it, and with that kind of quality I outline above, even if we can't get or or two of them and switch it out, we really are looking like a title challenging club. We're really not that far off. Squad depth, lack thereof, and some instant improvements in key areas, plus a world class manager, is all that's holding us back here.
