It's funny how managers go so stale. Bilic was the best thing since sliced bread a year or so ago. Now he's inept, he'll get shown the door, a new guy will come in and they'll look like world beaters, he'll be the best thing since sliced bread. Fast forward a year or two and he'll be inept, new guy will come in...
Wash, rinse, repeat.
That's how it is generally with few exceptions I suppose, sad isn't it. Part of the gradual decline of our game.
