don't see how he can compare henderson to colback.
different positions, colback hasn't played enough games yet, (although looks decent in the one's he has played).
henderson is proven, and if i remember correctly, is younger than colback.
henderson has the r/w position to himself, and needs competition and replacements if he get's injured or a dip in form.
colback is one of a number of c/m, and isn't guaranteed to start anyway.
we need to keep both and make them the core of the team, and hope colback lives up to bruce's expectations and ours.
reckon there will be a bidding war for henderson, and there will be a breaking point where the club will say the offers to good to turn down. hope im wrong, but money is money, but finding a replacement is another story.
