I agree the bloke has not been given any real time to sort things out and it is a ridiculous decision.
However his tactics have left a lot to be desired and most of his signings have been disappointing to say the least.
As for Shearer. Why not give him a chance? He is as well if not better qualified than K. Keegan was when he took the job and let's face it the Keegan years were the most enjoyable by far in my lifetime as a fan.
Never given enough time, don't know what Newcastle fans were expecting, you have had a bad run but ur 11th still got a few cups involvements. Most managers need at least 1 to 1 1/2 seasons to gel with the players just look at Everton they struggled initially with Moyes but now are going really well.
