Highest points total in the PL and taking us to within two wins of our first trophy for 21 years would seem to suggest otherwise.
But on the squad: I think it's clear from your posts thus far that you believe that, not only is Martinez incapable of using it as it stands to obtain a CL spot, but any incoming manager would also struggle to secure a CL spot with it - hence the need for more purchases.
So there's a couple of things to emerge this week regarding your position:
1/ The failure to demonstrate why Martinez should be judged more harshly than previous Everton managers (poorer Everton managers one and all as measured by PL points performance and career win rate at the club) that he must walk the plank which no one else had to walk
and (relatedly)
2/ That the squad (the one you believe to be beyond question of such a quality that it amounts to a sackable offence not to utilise to gain a CL spot) is not going to be good enough after all to secure a CL place under the hypothetical new coach, who is to be superior to Martinez.
