Oh, I agree very much. I spent the majority of the January thread arguing against the need to buy a striker for the sake of it, so you're preaching to the choir. I think, it's essential that we only add (and ship off) a few players and do our research very well, at least as much in regards to the personality as the ability/potential of the incomings, and I think that's Poch's thinking as well.
Carvalho's name just popped up somewhere, and I got curious as to Nabil's thoughts on him and why he hasn't progressed, as he seemed a similar type of player to Dier, from what little I have seen of him. And I happen to think that someone who can perform the same role as Dier is one of the few incomings, we should have. Barring that someone from the academy can fulfill the role.
