First of all, we must keep him. Selling him in this window would be inexcusable. There is nothing to lose and everything to gain with him in terms of value, as well as contribution on the pitch.
His presence should prevent us signing another attacking midfielder along with (hopefully) Holmes. The likes of Carey and Reeves were/are available on frees but as tempting as it might be to sign certain players, we can't be flooding the midfield to an extent where Brooks' path to the team is completely shut off.
He's a special talent and if we can't significantly factor him into our plans this season, then I don't know when an academy player will ever get a chance in the first team.
Put it this way, if he played for another club we wouldn't have a hope in hell of signing him. We need to realise what sort of asset we've got and try to maximise it, for once.
He's an option anywhere across attacking midfield, right wing is probably his best bet at this stage. He'd suit a 4-2-3-1. As he develops I could see him becoming our best option for the number 10 position.
I just want to see how good he is, how good he can become, and see him in our first team, at least for one season. Then if we do sell him, get proper money. That shouldn't be too much to ask.
