How about
Walker (26 yrs) £50m
Rose (26yrs) £50
Pickford (23 yrs) £20
VVD (25 yrs) £50
Kieran Tierney (19 yrs) £20m
Eric Dier (23 yrs) or Weigl (21 yrs) £50
Gross spend=£240 with an English backbone.
Sell Hart, Bravo, Nolito, Mangala, Bony, Nasri; Fernando, Delph and maybe Iheanacho for about £80m
Add the £10m remaining from the original £250 (that they say Pep will have) to the £80m or whatever we can get from the sales of these players, and you get £90m more spend.
Then bring back Maffeo (19 yrs) and maybe Enes Unal (19 yrs).
Then we'll have
GK: Pickford/Rulli
RB: Walker/Maffeo
CB: VVD/Kompany/Stones/Otamendi/Kolarov
LB: Rose/Kieran
DM: Dier or Weigl/Yaya/Fernandinho/Gundogan/Garcia
CM: De Bruyne/Silva/Gundogan/Fernandinho/Yaya/Foden/Diaz
FW: Sterling/Sane/Aguero/Jesus/Unal/Sancho
We could use that additional £90-100 for someone up front like Sanchez (or someone else) or for another creative midfielder like Isco (or someone like him).
Just in theory, doesn't work in real life.
