OK let's put these to bed Dave
1)Martinez is being judged on the following criteria (i) he inherited in his own words "a great platform" from which to progress - we haven't progressed we've moved backwards in absolute and relative terms (ii) he's added well to the squad (just to show balance, as I say he has some skills) so the squad has improved but sadly results have not and there's no evidence in the PL of any change to this trend; (iii) the PL landscape has changed, the glass ceiling that existed predominantly in Moyes' days no longer exists due to a combination of increased investment in a wider number of clubs, the decline of previous incumbents in Manchester United, Chelsea, Liverpool and this season Manchester City, and the tactical astuteness and man management skills of managers such as Ranieri, Pochettino and Bilic. The glaring omission in contenders is our very own Everton.
2) As I've stated on many occasions our current squad is strong enough to compete in the current race for CL positions, that's almost universally acknowledged across the football community - I do not differ from that point of view at all. However I also realise that we must invest further and restructure the squad to increase our competitiveness particularly (i) if we wish to move from a top 4 challenger to a title challenger, and from a CL qualifier to a CL knock-out stage contender, and (ii) in the light of other clubs' spending plans, we must invest and restructure just to stand still. To not do so would mean in relative terms we move backwards - something we saw time and time again in the dark days of no funding being available for squad development under Moyes.
Now should we do this under a manager who has failed to fashion results out of our existing talents and has proven to be unable to compete at the higher levels our current squad suggests, let alone, an enhanced squad at even higher levels, or should we use our new purchasing power to acquire more skilled, more experienced, already proven management who can not only retain existing talent, but enhance and add to it?
It's a no brainer. It's not personal - we'll all wish Martinez the very best, and if he manages to secure a FA Cup win he'll be part of our folklore forever, but he's not the man to take us forward in the current environment and make the best of the opportunities ahead of us.
I cannot be clearer than that - I'm not asking you to agree necessarily as you're clearly of a singular view that Martinez is the man to achieve all we wish for, but you must accept the logic of the position I and many others propose.
