Dodgy knees. I have stared at your avatar for some time now... and I must say, I'm pretty certain those are not knees.
I think GH should stay for now, sign no-one until august when he sanctions bringing in a checkered player that doesn't want to be here in partial trade for our best player. Then, he should leave unannounced, in a snit, 5 days before the season, with the club still on an unsustainable wage bill. Oh, and take most of the coaching staff with him. That will set up the next guy for great success. Oh, and then have a caretaker who's a "nice guy" to make certain the players resent discipline when the new guy arrives. (I'm sorry, I know I'm not on the script here, but I couldn't help myself.)
