keep Hamer(God) at all costs i would say
The gamble - if there was one, for me - would be to get what we could for Vik, then gamble on Gus being able to drive the team up the table. Keep him (even if he won't sign a new contract) and rebuild the rest of the team with Vik's money. Wouldn't need to spend a penny on midfield, as we'd have Hamer, Sheaf, Palmer, Allen, Eccles, O'Hare (perhaps Kelly) . We could then buy a couple of decent strikers, reshape our defence, partly through Vik's money and the clearance of the Walkers, Waghorns and all the other out of contract players. The downside is losing Gus for nothing, but if we made the PL it would be paid for x 20-30. Obviously if we got offered a huge amount for Gus, then we'd have to take it, but it must be near a £10m figure imo; he's that good.
