Manchester United and Alex Ferguson remind me a bit of myself and my old Austin Allegro. I knew the car was old and would pack in anyday but I still ran it into the ground until it did. Luckily I was at a roundabout doing approx 2mph when it finally conked out on me.The point is,how much more are United going to rely on Sir Alex? When is he going to retire and more importantly,who would be an ideal replacement for him?
