I'd be a lot more keen if it was someone integral to the team like Coutts, Duffy or Fleck (although obviously no one will pay that amount of money for any of them), but as Brooks is a bit part player at the moment at best, I see no reason to bring him back and do the development work for whomever buys him.
I'll probably regret that when he gets farmed out to a rival and shoots them to the top of the league, mind.
