There isn't a lot I can argue with there. I totally appreciate and understand those who share your views.
The only thing I don't understand totally is the assertion that the only way we can progress is to bin him.
I believe with proper investment (which we now have), Martinez has the abilities to build a side which play expressive, dynamic football which will get us challenging consistently.
Its now over to him to prove me right (or wrong).
I can see where you are coming from mate and yes it is in his hands but therein lies the difficulty. In your other post you talked of allowing until Xmas. You also mentioned his "rebuilding" programme, a project of upto 5 years of which 3 have passed apart from a few games. The problem with his project is that if we fail to retain certain players - Rom, Ross, John then it will be like starting all over again from ground zero. If that were to happen is waiting until Xmas realistic to make a judgement on his performance.
As for how you say proper investment, not sure how much funds will be available or if RM can be allowed to spend that.
For me I have just not seen any evidence that RM has it in him to take this club upwards unlike you. I am not convinced he has the ability to which you refer and if you are talking of allowing until Xmas then it must be that you are not 100% sure either so some doubt must exist in your mind.
