Hoilett would cost 15m+ because he's 20, has 2 or 3 years left on his deal and is HIGHLY treasured by BRFC. His only drawback is that he's Canadian (blame Canada, etc.)
Nzogbia is a good player...but we need to be very careful. If he has 1 great year he'll demand a move. The guy is also a bit of a nutcase, see Ireland. If we can get him for 10m or less, fine. If not, it starts to become a riskier move.
