Clyne must be of greater value than Chicarito who isn't rated good enough for Manure and can't get a game in Spain.
So for me £10-15m + Chicarito. This will give us enough for a goos replacement (or two)
Hernandez must be worth £10-15m, and I don't see Nat as £25-30m. I think Nat is about £15m maybe with a few bidding that could nudge up a bit towards £20m max. This would then make a swap deal plus about £5m maybe.
