Top keeper was Nev and no doubt a massive (and rapidly expanding) blue but he's a bit of a thicko and seems to revel in being a bit controversial.
I don't think he is tryng to be controversial in this blog, quite reasonable and thought out.
Martinez wouldn't get 50mil though. No world class player would join. If 28 gets you Rom ( I know its not 28m straightup) then its gonna get 2 maybe 3 decent-ish players tops.
Hazard and Erickson cost about 32m and 12m respectively. That would leave some left over for signing on fees etc and signings of that calibre would improve the squad. Obviously it's a risk but it is possible. I wouldn't say either were considered world class when they signed, but Hazard is and Erickson is potentially.
Then you also have to consider wages as well. Everything following is direct silly season FIFA nonsense...
Even if we got 50-60 mil for Ross we'd be adding a lot of wages to consider. It's just not a smart move really.
Out-50 m Ross
In- van Dijk 10m
Shaqiri 15m
KDB or Pjanic- 25m
Marshall - money from mls for Timmy.
Not to mention teams would know we need to spend to replace Ross and would up their demands
Say you brought in Shaqiri and Pjanic hoping they could perform something like Hazard and Erickson. Obviously there is big wages there but there is still a bit of deadwood about the squad.
I'm not advocating the sale, just saying it's possible that we can do it and improve. Risk / Reward.
