Everton manager Ronald Koeman has been backed by majority shareholder Farhad Moshiri after Sunday's 1-0 home defeat to Burnley.
Koeman spent around £150 million over the summer, but his side have picked up only seven points from seven league matches and are also struggling in the Europa League.
Moshiri told Sky Sports: "We're in a bad moment -- but we have played the four title contenders, three away.
"Today was the only unexpected loss. The four pre-qualifying UEFA [Europa League] games and two group games on Thursdays haven't helped.
"There is mental and physical fatigue, and seven injuries.
