It was inevitable really, wasn't it?Everton have relieved Ronald Koeman of his duties in the wake of their 5-2 defeat at home to Arsenal.Instead of delivering total football, the Dutchman unleashed total chaos at Goodison Park, departing with the Toffees 18th in the Premier League.The former Southampton boss was given a huge budget and spent over £150million this summer alone.Bill Kenwright and Fahrad Moshiri weren't expecting fireworks; all they asked is that he finally broke into the top six.However, the loss of Romelu Lukaku to Manchester United proved too much to handle, as the Belgian was never properly replaced.Add that to Jordan Pickford struggling to settle and the poor form of Ashley Williams, and Everton's position in the table starts to make a little more sense.Few will have been surprised by the announcement on Monday afternoon that Koeman had parted ways with the club, least of all the man himself, who was pictured enjoying a night on the town just hours after the Arsenal game. You get the feeling he knew he wasn't going to be preparing for Chelsea in the Carabao Cup on Wednesday.After all, the Premier League is a cutthroat business, as Frank de Boer and Craig Shakespeare have already learned this season.

Lineker responds 

Gary Lineker picked up on that with his reaction to Koeman's sacking:

As several Twitter users were keen to point out, though, he fully deserved to go, even if it's a little alarming that we've already lost three managers so early into the campaign.

Attention now turns to what the board will do next.

The Mirror reported on Sunday that David Moyes was the early favourite to succeed Koeman, having enjoyed 11 years on Merseyside prior to replacing Sir Alex Ferguson at Manchester United in 2013.

Under-23 coach David Unsworth is another name in the frame. Koeman never quite seemed to 'get' Everton, and in Unsworth, they have a man who knows the club inside out.

What's next for Koeman? One gets the feeling that his dream job at Barcelona is on hold for now, and he leaves with his reputation diminished.

On the bright side, he wasn't the first top-flight manager to lose his job this season and it seems very unlikely that he'll be the last.
