If we receive an offer of 6.5 million (like last season) this coming January I'd hope the club accepts it. If Hoban is fully fit and can remain injury free - he'd be a fantastic replacement.
I'd be happy to see us spend some money on either Jason Kerr or Stuart Findlay although I don't know if we could afford them. Invest the rest of the fee into the new stadium.
Both Cosgrove and Ferguson will most likely remain for another season or two before heading down south for a decent fee. Again put aside some money for new signings and put the rest into the new stadium.
