Returning to Martinez, the discussion as to whether he is our best PL manager is some what of a red herring. He can be the best we have had but still fall short of the requirements of someone suitable to meet stated objectives. "Best" is a relative term, and actually we need to deal in absolutes not relative measures.
In absolute terms Martinez has demonstrated he does not possess the necessary skills to manage a team consistently competing for the CL places.
I contend, and this has not been countered by anyone who believes Martinez to be the suitable candidate, that
(i) he lacks the ability to instil belief in his players, the evidence of increased mental fragility is not only evident on the pitch but in his post match comments:
"Clearly the psychological aspect of going into a game is not right at the moment. We feel we can let our fans down, that we’ve got something to lose…the doubts, the communication is not what it should be. And that’s something that’s affecting our scorelines."
"Our performance .......clearly shows we need to learn how to play at home in the league."
(ii) he lacks tactical awareness and the ability to change the course of a game through change of tactics or personnel,
and
(iii) he lacks the ability to organise a team defensively, and improve individual defenders.
Re comments as to the unrealistic and too lofty expectations put upon our manger, ie competing for CL qualification, why is that unrealistic and/or too lofty given the quality of players at our disposal, and the fact that lesser squads with more effective management and coaching are currently occupying 3 of the top 5 places in the Premier League?
