I understand where you are coming from but I wouldnt want us following the example of Spurs or them lot in their hiring & firing policies, and Man U operate on a different level to us really as they can shovel cash into a problem.
Its not a stretch to think back over your time watching football and remember managers who had a bad season or even failed at one club, before coming back stronger and being a success. We all know this happens, so I don´t think it should be difficult to understand some peoples view that he be given more time. If he is being judged by this season to the level that people want him sacked, then he can be judged on last in the opposite way....and therein you have the balance and the reasoning why myself and others want us to stick with him.
I view this season as a hole that we fell further and further into and that all decision making, performances and results are greatly affected by the position we have found ourselves in and have not had a moments respite or luck to drag us out. Everything is tainted by this atmosphere of fear and low confidence. I don´t think some of the more grating of decisions by the boss, and performances by some of our regulars will be as likely given the light and optimism of a new season with the inevitable refresh of the squad which is clearly and badly needed (although i can totally understand some peoples fears of allowing Martinez to make further signings if they expect him to be gone regardless next season).
