Previous manager is given three years, runs squad into the ground by buying in dross, failing to replace players reaching the end of their careers and generally lowering the profile of the club.... New manager is judged a failure for not turning it all around in 15 games.
What kind of impatient, entitled fanbase behaves this way? I'll take your point re the league table being more concrete than Martinez-style happy-clappy PR-talk, but why are you judging Koeman after 15 games?
Koeman is still working with what is, bar FOUR players, the squad he inherited from Martinez. The four he signed are all upgrades in their respective positions. The manager is making progress and yes, I would love to see more progress too - but I'm not foolish and petulant enough to demand a new manager after FIFTEEN games just because we aren't fifth in a league that includes several of the planet's richest clubs.
Moshiri needs time. Koeman needs time. You were all happy to give Martinez two seasons (some people were happy giving him three!) but you expect the fallout of the Martinez era to be tidied away and cured completely in FIFTEEN games? I'll be polite and simply say you, and others like you, are being unrealistic.
