He's not getting sacked, so the gnashing is for literally nothing.
This is a very young team, and in any sport a young team will be inconsistent while it learns. It will produce moments of brilliant flair but lacks tactical understanding. Every young athlete is like this.
I can't remember too many games that we've been second best in this season. Most of the games we've lost, we've outplayed our opponents and lost to moments of naivety or madness. Most of those indiscretions fall on Martinez's shoulders, but so too does the fact the team played well enough to be in a winning position in the first place.
This season has been so close to being a good one. The Bournemouth game remains my tipping point - we claim a last gasp win there, morale explodes and we kick on after an excellent few weeks. But from then on, the team has lacked belief and fortitude.
People are right when they say this team is close to something excellent. People are right when they say the manager is responsible for parts of the disappointment this season (and even moreso last season). Nobody is right in suggesting he is close to losing his job, that's just the reality of the club at present.
It's not easy some weeks, but all we can do is watch it unfold. He might bring the best out of some rising stars, tidy up the few lingering issues and see us really kick on. He might be brought completely undone by stubbornness and his tactical failings. Either way, the end game is some time away from now, rendering the debate largely pointless.
