That may well be the case SB but following CW getting stung last year by taking similar risks on thinking the better L1 players would be able to make the step-up and the constrained budget he's working to, I'd be amazed if he decides to take a £1m+ risk on Maddison.
With Dowell in and Madine on the verge of being confirmed, I'd have thought the next position to recruit to would be CB. Egan has been a rock but with Wright on his way out and Stearman looking way off, perhaps additional cover/competition is required, especially if a left-footer is recruited who could potentially also cover JOC and even Stevens as Bryan still looks to be a way-off full fitness following his injuries.
