There's a stock explanation behind Everton's decision to pursue, and appoint, Carlo Ancelotti as their new manager. The Toffees are ambitious and willing to spend enormous amounts of money to achieve, and maintain, elite status. Given that Ancelotti has managed more elite clubs than you can shake a stick at -- from Milan to Real Madrid, from Bayern to Paris Saint-Germain, from Juventus to Chelsea -- Everton are automatically on their way with their elite manager.
Of course, this kind of (flawed) logic raises several more questions.
One is the obvious cart-before-horse argument. The past five clubs Ancelotti managed finished first, second or third before his arrival; Everton haven't finished that high since 1987 and haven't finished higher than seventh in the past five years.
