I would imagine the pragmatic side of John Henry is currently looking at the situation and the malaise that the squad seems to be in and thinking very hard about making anything available.
There's no guarantee that a big player like Suarez would alter the morale of the squad but it could be £15-17m down the toilet if we can't pull out of this downward spiral. Relegation, whether we like it or not, is a real possibility if some of our players don't pull their fucking finger out.
