Well, what if Bruno doesn't get an injury and doesn't struggle in the prem? Then you'll have either one player who's very unhappy because he plays very little, or two players who are unhappy because neither of them play as much as they should. And additionally, a DvdB who doesn't fit anywhere and probably doesn't play at all. All this while there are screaming uncovered needs at almost every other position.
That someone might be useful doesn't cut it - we have so many needs in so many areas that there's got to be some sense of priority here. Going after a player because he's a good player and then sorting out afterwards how to shuffle the pieces is the very essence of a deficient transfer strategy, and exactly what we should be moving away from.
