I may be in the minority here, but i don't believe Lampards sacking is harsh.
If you back at his jobs as manager, he took Derby from 3rd...to 3rd, Chelsea from 6th....to 6th. Now spent over £200m on players who he can't get a tune out of. It was only ever going to end badly, that sort of money demands instant results.
Lets be honest though, I don't think he expected the Chelsea job so early, it was always going to be end game.
Hopefully he can get another job in the Championship, prove his worth as a manager then push back on.
