Found it - they just quoted him in a piece they did about Chelsea loanees this season.
As I say, from watching Brown last season I thought he was very much a midfielder but apparently he did play up front for Rotherham before that.
I agree I think he's a really good signing but I still think we still need an absolute minimum of one and ideally two more out and out strikers and three if Hemed does go.
From memory I think it was a Sky Sports piece where he said something like Brown would give us more options alongside our exisiting strikers. Just surprised me as I thought he was more of an attacking midfielder.
