There has been a serious lack of "world class" players at Everton. Even the 1980s side lacked players that you could seriously say were internationally world-class (or considered so by other club supporters).
In my life time I would say:
Nev
Kanchelskis
Lineker
At a push - Trevor Steven
Rooney Mk I for the short time he was here.
Its a bit of an embarassment, when you look at other Premier League sides such as Spurs who have always seem to have world class players to enjoy eg Bale, Ginola, Sheringham, Berbatov, Kane, Klinsman ect ect.
When the going is good, the Everton has always been greater than its sum of parts. Kendall (1980s version) did this, Joe Royle did this for a season, and Moyes did this (his squads were grossly underfunded in comparison to where they finished). If you think of the Everton way, I would say teamwork, hardwork and a splattering of real quality but no overpaid prima donnas.
We have taken a wrong turn with the new money are we not buying players or finding managers to fit our system.
