Rumours are, not a penny less than £35 million, and that is exactly where we should stubbornly dig in.
Regardless of whether this club has been able to get the best out of him or not, he is a top player, he's young, and a full and regular international for a decent international team.
I'm pretty sure that our fans hero Kevin McCabe would have accepted £10 million and a 10% sell on and not stopped pulling his pud for the entire summer as we replaced him with Sam Clucas on a free.
£35 - £40 million is a reasonable fee to demand for him even if some of our fans can't believe that we could have such a player.
