Martinez should be doing slightly better but I believe this Everton side is massively overrated. Toffee fans seems to think they've got a top four squad LOL. When Barry, Cleverly, Gibson, Kone, Jagielka, Lennon & Mori are important players you're a far way off top four. 10th is a fair position for their quality and other sides. Consider Stoke, Southampton, West Ham and ourselves, they're of the same level all things considered.
To be fair, I don't know a single Everton fan who think they have a top 4 squad, and I know a fair few of them. He might pretend he does for WUM purposes but even johnnytodd doesn't believe that. They should easily be challenging for the Europa spots though.
Martinez is as bad as I said he was when he took over and flattered to deceive in his first season. The longer he stays the better.
