The final whistle sounded and a chorus of boos greeted it, with Koeman swiftly sloping off down the tunnel as he prepares himself for the tough questions and major scrutiny he will now face after guiding Everton to 4 league losses from 7 games.
"Today was the only unexpected loss".
Having managed just seven points and one victory away from home last season, Burnley's 1-0 win at Everton on Sunday ensured their best start on the road in a top flight campaign since 1966.
On Thursday (28 September), after Everton conceded a late equaliser to draw 2-2 against Apollon Limassol in the Europa League, Koeman admitted his side were "afraid to play football" and acknowledged they would go into the worldwide break on a very downbeat note.
Furthermore, the Italian newspaper there's every chance the 56-year-old could travel to Liverpool in the next few days, presumably for talks with Everton.
Everton are set to approach Walter Mazzarri this week with Ronald Koeman's position at Goodison Park looking precarious.

In the days that followed the president issued a series of tweets reiterating his views and calling for a fan boycott of games. Three teams - Pittsburgh, Seattle and Tennessee - did not take the field until after the anthem.
The Everton hierarchy were well aware of Lukaku's intentions to leave before the end of last season and had time to locate an alternative striker once Olivier Giroud, Koeman's preferred target, made a decision to stay at Arsenal.
"I can't complain about my players", Koeman said. If there is no commitment and no aggression, that is maybe a reason to think about the future.
Everton will try to mend things in January when they are expected to make a move for a classic striker and that's where West Ham forward Andy Carroll steps in.
"I do not like to see managers lose their jobs, particularly early in the season", he wrote in the Daily Mail. The fans all know the talent our players have which is why it is so bemusing they are performing so poorly. "Wardy has done great, pulled it back to me and luckily it went in".
"I think honestly that Ronald Koeman has done some very, very good business in the transfer market with getting Sigurdsson as well", he told The Alan Brazil Sports Breakfast on talkSPORT (broadcast on 2nd October 2017; 6:20 am). "We needed to be at our best to create and we didn't create a lot".
